Costco April 2026 Products Coupon Book Delivers Discounts on Diapers, Protein Supplements and Lawn Gear

Costco members began receiving the April 2026 Member-Only Savings Book in mailboxes and at warehouse service desks over the past week. The booklet provides instant savings on hundreds of items and runs from April 6 through May 3, 2026.

Update: Now you can Download the Complete Booklet.

Deals apply automatically at checkout for in-warehouse and eligible online purchases once the sale period starts.

No separate coupons are required, and most items carry purchase limits to stretch availability across the membership base.

Previews of the book, compiled by sites that receive advance copies, show a larger format than recent editions and a strong emphasis on spring-related categories such as lawn and garden supplies, allergy relief, baby essentials and select grocery staples.

Among the standout offers are $100 off the Greenworks 80-volt 21-inch self-propelled mower, $10 off Huggies Plus Little Snugglers diapers (bringing a common size pack to $29.99) and $10 off Pampers Swaddlers Ultra diapers.

Protein supplements receive notable cuts, with Orgain Micronized Creatine Monohydrate Powder dropping $5 to $14.99 and the Ascent Whey Protein Blend reduced by $13 to $38.99.

Kerrygold Pure Irish Butter falls $4.30 to $12.69 for a four-pack, while Rao’s Homemade Marinara Sauce two-pack saves $3.30.

Additional savings cover household staples such as Bounty paper towels, Tide and Gain laundry products, Lysol wipes and oral care items from Colgate, Listerine and Philips Sonicare.

Allergy medications including Kirkland Signature AllerClear, Claritin and Flonase also appear with reductions ranging from $3 to $11.

Tire buyers can claim $80 off any set of four Michelin models, and several major appliances from KitchenAid, Vitamix, Dyson and select LG, Whirlpool and Samsung lines carry triple-digit discounts.

At the same time, Costco warehouses have begun rolling out new spring inventory separate from the coupon book.

Early April arrivals include SUNSET WOW Dreamberry strawberries in limited Mother’s Day packaging, DeeBee’s Organics SuperFruit Freezies, JonnyPops Organic Rainbow Fruit Stacks and Crepini Vanilla Protein Pancakes.

Seasonal snacks such as Goldfish Butterbeer Flavored Grahams, Loacker Spring Minis Mix and GODIVA Premium Assortment Spring chocolate boxes have also appeared in select regions.

These product rotations and the coupon book follow Costco’s established monthly schedule. The March booklet ends March 29, leaving a brief gap before April deals activate.

Regional variations in stock and pricing remain common, so members are advised to check local warehouses or the Costco app for exact availability once the sale begins.

The savings run through the first weekend in May, aligning with continued spring demand for outdoor and household refresh items.
