Welcome to the Weekly Cashback Deals Roundup for August 17–23, 2026, from CashbackIndex. As the back-to-school rush winds down and retailers shift into end-of-summer clearance mode, shoppers can find deep discounts on leftover school supplies, summer apparel, and seasonal home goods. This week features fresh promo codes, steady cashback rates, and clearance events across every major online retailer. Here’s your complete guide.
Walmart: 25% Off Code + $15 Off Sitewide
Walmart is kicking off the week with two strong promo codes: POTION25 for 25% off your purchase and BUSINESS15 for $15 off a sitewide purchase. The retailer currently has 29 active promo codes, including free shipping offers and a student discount. Cashback sits at a steady 4% on everyday low prices, with elevated rates available on select categories. End-of-summer clearance is hitting hard on patio furniture, grills, and seasonal décor, while leftover back-to-school supplies are being marked down to make room for fall inventory.
Amazon: Up to 80% Off + Prime Exclusive Perks
Amazon is offering up to 80% off across categories this week, with clippable coupons adding up to 20% off on health, personal care, grocery, beauty, office supplies, and electronics. Prime members can also grab a new perk: $10 off their first $20+ Grubhub order through the Prime + Grubhub partnership. Daily deals and lightning deals continue to rotate, and post-back-to-school tech is seeing some of the lowest prices of the year as demand cools. Always start your Amazon session at CashbackIndex to capture every available cashback rebate.
Target: Extra 25% Off Select Items + 2% Cashback
Target is running an extra 25% off select items with a verified promo code, plus up to $20 off through Target Circle Deals. CashbackIndex users earn a steady 2% cashback sitewide, and Target Circle Card holders save an automatic 5% on every purchase. With 40 verified offers active this week, there are plenty of ways to stack savings. End-of-summer clearance on swimwear, outdoor gear, and summer apparel is reaching 50–70% off, while fall clothing lines are just starting to appear at full price – so now is the time to grab summer staples on the cheap.
Best Buy: Member Deals 30%+ Off + 3% Cashback
Best Buy’s My Best Buy members continue to access 30% off or more on select tech, with a reliable 3% cashback on all online purchases. The clearance section is running up to 50% off, and with 32 verified offers active as of this weekend, there are solid deals on laptops, TVs, headphones, and smart home devices. As back-to-school tech demand tapers off, expect prices on laptops and tablets to drop further through the end of August – this is a great window for anyone who didn’t shop during the peak back-to-school rush.
Macy’s: 30% Off August Deals + Cashback Up to 6%
Macy’s August promotion continues with 30% off across departments, and new text-signup subscribers get an extra 25% off their first order. Cashback rates are competitive this week, with some portals offering up to 6% cashback on all other categories – a significant jump from the standard rate. End-of-summer clearance is in full swing on swimwear, sandals, and warm-weather apparel, while fall fashion is beginning to arrive. Star Rewards members get free shipping on orders over $39, making it easy to combine clearance finds with elevated cashback for maximum savings.
eBay: 38 Verified Offers + Spotlight Deals
eBay has 38 verified offers active this week, with Spotlight Deals continuing to deliver deep discounts across electronics, fashion, and home goods. Certified refurbished electronics remain one of the best value plays for budget shoppers, and auction-style listings can yield unexpected bargains on everything from designer bags to power tools. CashbackIndex users earn rebates on all eligible eBay purchases, adding another layer of savings to already discounted prices. With the back-to-school promo code expired, this week’s eBay deals lean more toward general clearance and end-of-season markdowns.
