Costco is currently running its April 2026 Member-Only Savings event, offering substantial discounts across several high-demand categories including health supplements, spring gardening gear, tires, and pantry staples. These deals are active right now and will remain valid through May 3, 2026. Whether you are shopping in-warehouse or browsing the online portal, this period represents one of the strongest savings windows before the early summer rush.

The current promotional cycle features over 125 individual deals, with a heavy emphasis on seasonal transitions. As pollen counts rise and homeowners begin their lawn preparations, the savings on allergy relief and power equipment are particularly strategic.

Current Highlights of the April 2026 Savings Event

The core of this week's savings can be found in the monthly coupon booklet, which members usually receive via mail or the mobile app. The standout offers for the current window include significant markdowns on major brands and Kirkland Signature alternatives.

Essential Health and Allergy Relief Markdowns

Late April marks the height of the spring allergy season in many regions, and Costco has responded by discounting almost every major allergy medication in their pharmacy section.

  • Kirkland Signature Aller-Tec and Aller-Flo: These are currently seeing deep discounts. In our comparison tests, the Aller-Flo (fluticasone propionate) provides identical relief to name-brand Flonase at a fraction of the cost, especially with the current $5 to $8 off the multi-pack.
  • Zyrtec and Claritin: For those who prefer the original brands, 100-count bottles are currently discounted by up to $10.
  • Orgain Organic Protein Powder: A staple for many fitness enthusiasts, the 2.03 lb containers are $10 off. Based on our experience, the vanilla bean flavor mixes significantly smoother in plant-based milks compared to the chocolate fudge variant during this batch's production.

Spring Lawn and Garden Power Equipment

With the growing season in full swing, the middle aisles of the warehouse are packed with Greenworks and Miracle-Gro products.

  • Greenworks 80V Mower and Blower: These high-voltage tools are currently part of a bundle promotion. The 80V self-propelled mower, which we have tested on half-acre lots, offers a consistent 45-minute runtime. During this sale, members can save $100 to $150 on the full kit, which includes two batteries.
  • Miracle-Gro Potting Mix and Garden Soil: Buying these in bulk (55-quart bags) is a common April ritual. The current "Buy 3, Save $15" style promotions make it much cheaper than local hardware stores.
  • Lettuce Grow Farmstand: This vertical hydroponic system has become a trendy addition to the Costco floor. It is currently featured at a promotional introductory price, making it a viable option for members with limited backyard space who still want to grow their own kale and herbs.

Tire Center Promotions and Maintenance Perks

One of the most valuable consistent deals at Costco is the rotating tire brand discount. From now until May 3, the spotlight is on Michelin.

Why the Michelin $80 Off Deal Matters

Members can currently get $80 off a set of four Michelin tires. While this promotion appears several times a year, the April window is ideal for those swapping out winter tires for all-season performance.

The value isn't just in the $80 sticker price reduction. When you purchase through the Costco Tire Center, the installation package (typically $18.99 per tire) includes lifetime rotation, lifetime balancing, and nitrogen inflation. In our analysis of long-term vehicle maintenance, the nitrogen inflation alone helps maintain more consistent tire pressure during the fluctuating temperatures of spring, potentially extending the tread life by 10% compared to standard compressed air.

Navigating the Tire Appointment System

If you plan to take advantage of the Michelin sale this week, we recommend using the online booking tool at least 48 hours in advance. Warehouse walk-ins during a major sale week often face wait times exceeding three hours. If you are ordering a specific size not currently in stock at your local warehouse, the shipping time to the store usually takes 5 to 7 business days, but you can still lock in the current sale price as long as the order is placed before May 3.

Household Essentials and Pantry Stock-Up Deals

The April savings book is heavy on cleaning supplies and bulk food items that rarely go on sale simultaneously.

Kitchen and Pantry Staples

  • Kerrygold Pure Irish Butter: This fan-favorite is currently discounted for the 3-pack of 8 oz bars. For those who bake, the high fat content of Kerrygold makes a noticeable difference in the flakiness of pie crusts compared to standard AA butter.
  • Royal Asia Prawn Hacao: In the frozen section, these shrimp dumplings are $4 off. We’ve found that steaming them for exactly six minutes yields a texture comparable to high-end dim sum restaurants.
  • Kirkland Signature K-Cups: Various roasts, including the Pacific Bold and Breakfast Blend, are seeing a $5 discount per 120-count box.

Cleaning and Baby Supplies

  • Huggies and Pampers: Both major brands often have competing sales during the April event. Currently, Huggies Plus diapers and wipes are seeing a "Buy 2, Save $10" promotion.
  • Cleaning Bundles: Clorox Disinfecting Wipes and Dawn Platinum Powerwash are featured items. The Dawn Powerwash starter kit is particularly useful for pre-treating outdoor grill grates before the summer barbecue season begins.

How to Find Secret Unadvertised Clearance Deals

While the coupon book covers the advertised "Member-Only Savings," the real treasures are the unadvertised markdowns found only by walking the aisles. This week, we noticed several trends in the "Treasure Hunt" category.

The Power of the Asterisk

When browsing the aisles this week, pay close attention to the top right corner of the price tag. If you see an asterisk (*), it means the item is discontinued and will not be restocked once the current inventory is gone.

In late April, we are seeing the asterisk on winter clearance items like heavy flannel shirts, snow shovels, and indoor space heaters. These items are often marked down to prices ending in .97, which signifies a corporate-level clearance price. For example, a high-quality puffer vest that was $29.99 in November might be sitting on an end-cap for $9.97 this week.

End-of-Aisle Displays and Floor Models

The "end-caps" (the displays at the end of each aisle) are prime real estate for immediate inventory moves. This week, many warehouses are clearing out floor models of indoor furniture to make room for the massive influx of patio sets and gazebos. If you see a dining table or a sofa with a "Floor Model" tag, you can often negotiate an additional discount with the floor manager, especially if there is minor cosmetic wear.

Digital Tools for Tracking Costco Sales

To maximize your efficiency this week, the Costco mobile app is more than just a digital membership card. It has become a critical tool for inventory management.

Checking Local Warehouse Inventory

Not every deal listed in the April booklet is available at every location. The app now allows you to set your "Primary Warehouse" and search for specific items. If a deal like the MSI Thin 15 Gaming Laptop (which saw a $300 discount recently) is showing as "Out of Stock" at your main location, the app can often point you to a nearby warehouse that still has units on the floor.

Online vs. In-Warehouse Pricing

A common point of confusion for members is the price discrepancy between the website and the physical store. Most items listed on Costco.com include shipping and handling in the price, making them $2 to $10 more expensive than the in-store price. However, for large appliances and furniture, the online price often includes "White Glove Delivery" and installation, which provides superior value compared to trying to transport a 75-inch Sony Bravia TV in a personal vehicle.

Strategies for a Successful Shopping Trip This Week

Given the popularity of the April savings event, the warehouses are expected to be crowded, especially as we approach the May 3 deadline.

  1. Shop Mid-Week: Tuesday and Wednesday mornings between 10:00 AM and 12:00 PM are historically the quietest times. Avoid the "weekend warrior" rush where checkout lines can stretch into the snack aisles.
  2. Verify Item Numbers: If you are looking for a specific item mentioned in a review, such as the Sony 65-inch Bravia 3C, keep the item number (e.g., 9593565) handy. Employees can use this number to check the "In-Transit" status of new stock.
  3. The Price Adjustment Policy: If you bought an item last week at full price and it is now on sale for the April event, Costco generally offers a 30-day price adjustment. Bring your receipt to the membership desk to claim the difference.

What is the Costco price adjustment policy?

Costco offers a generous price adjustment policy for its members. If you purchase an item and it goes on sale within 30 days of your purchase, you can typically request a refund for the price difference. This applies to both in-warehouse and online purchases, though the requests must be handled in the respective channel where the purchase was made. For in-warehouse purchases, you simply visit the membership desk with your receipt. For online orders, there is a dedicated "Price Adjustment" form on the Costco website. Note that Costco does not price-match other retailers; they only adjust prices for their own internal markdowns.

How can I see the Costco ad for next week?

Costco typically does not release a "weekly" ad in the traditional sense like a grocery store. Instead, they operate on a "Member-Only Savings" cycle that lasts about 3-4 weeks. The current cycle ends on May 3, 2026. The next flyer is usually leaked on enthusiast sites like Costco Insider about a week before the current one expires, and the official digital version appears in the Costco app a few days prior to the start of the new period. To stay ahead, check the "Upcoming Savings" section in your account portal on the final weekend of the current sale.

Summary of Key Deals and Dates

To recap, the primary savings window is active until May 3, 2026.

  • Health: Stock up on Kirkland Signature allergy meds (Aller-Tec/Aller-Flo).
  • Outdoor: Look for $100+ savings on Greenworks 80V power tools.
  • Automotive: Take advantage of the $80 off Michelin tire set promotion.
  • Home: Use the "Asterisk" hunt to find .97 clearance prices on outgoing winter inventory.

Shopping at Costco this week requires a balance of following the advertised savings book and keeping a sharp eye out for unadvertised warehouse-specific clearances. By leveraging the app for inventory checks and timing your visit to avoid the weekend crowds, you can maximize the value of your membership during this final week of the April 2026 promotion.

Frequently Asked Questions

Can non-members buy items on sale at Costco?

Generally, no. The "Member-Only Savings" are strictly for those with an active Gold Star or Executive membership. However, non-members can shop on Costco.com for certain items, though they will be charged a 5% surcharge over the member price, which often negates the value of the sale. Another loophole is using a Costco Shop Card (gift card) provided by a member, which allows a non-member to enter and shop at warehouse prices.

Is the gas at Costco also on sale?

Costco Gas Stations do not participate in the "Member-Only Savings" booklet discounts. However, Costco gas is consistently priced significantly lower than surrounding branded stations. During high-traffic sale weeks, the gas lines can be long, so we recommend fueling up very early in the morning (stations usually open at 6:00 AM) or late in the evening after the warehouse has closed.

Does Costco offer a military or senior discount on memberships?

Costco does not offer a discounted membership fee for seniors or military personnel. However, they frequently run "New Member Promotions" for military, teachers, and students that include a Costco Shop Card (usually $20-$40) upon signing up.

What is the difference between the April savings and "Hot Buys"?

The April Member-Only Savings are month-long promotions. "Hot Buys" are shorter, unadvertised sales that usually last only 7-10 days and often bridge the gap between two monthly savings booklets. If you see a "Hot Buy" sign this week, it is likely a very limited-time offer on a specific grocery or apparel item that isn't in the main flyer.

Are the tire installation appointments free during the sale?

No, the installation fee is separate, but it is often discounted or bundled into the overall value of the tire promotion. For the current Michelin sale, the $80 discount applies to the tires themselves, while the lifetime maintenance package remains one of the most cost-effective ways to manage vehicle tires compared to third-party shops.
