Macy’s: Best of the Season Sale Ends September 28 – Only 5 Days Left
Macy’s flagship Best of the Season Sale is in its final stretch, ending September 28 – that’s only about five days away. The promotion delivers 30% off regular and already-reduced prices, plus 15% off beauty and fragrance. Star Rewards members earn $20 in Star Money for every $100 spent (that’s 2,000 bonus points) during the event. Additional highlights include Hotel Collection 5-star luxury bedding at up to 60% off, extra 30/15/10% off items labeled “BEST,” and app-only $20 or $30 off select items labeled APPFINDS. With the sale ending in just days, this is your last chance to grab fall fashion, outerwear, boots, home goods, and beauty at these prices before the next Friends & Family event later in the season. Macy’s standard 4% cashback continues through November 1, and Star Rewards members get free shipping on orders of $25 or more during the event. Start every Macy’s order through CashbackIndex to stack cashback on top of these deep discounts.
Walmart: Rare 50% Off Sitewide Code + 25% Off Code T25
Walmart is offering a rare 50% off sitewide promotion this week, alongside code T25 for 25% off sitewide and code T30 for up to 10% off qualifying items. With 50 total offers, 25 active coupon codes, and 7 free shipping deals, Walmart has one of its strongest promo lineups of the fall. Note that Walmart’s cashback remains at 1% this week (down from the recent 7.5% peak), so the value proposition continues to lean heavily on the discount codes rather than rebates. Walmart+ members enjoy free shipping with no minimum, while free shipping kicks in at $35 for everyone else. The retailer’s weekly flash deals continue with rotating discounts across electronics, home, fashion, and beauty. Post-summer clearance on patio, outdoor, and warm-weather items continues at deep discounts. Check the flash deals section daily, as new items are rotated in regularly.
Target: 25% Off Select Extended + 2% Cashback
Target’s popular 25% off select items promotion continues, now valid through January 1, 2027 – an unusually long window that positions it as a core fall/winter offering. A separate 25% off select items deal runs through October 16. Additional promotions include up to $20 off through Target Circle Deals and a steady 2% cashback sitewide through November 1. Target Circle Card holders save an automatic 5% on every purchase, and Circle members earn an additional 1% back in rewards. With 44–48 verified offers active, Target remains a reliable destination for fall home décor, transitional apparel, and seasonal essentials. The price match guarantee and same-day delivery/pickup options make it convenient for all shopping needs. Target app users can access exclusive coupons for up to 50% off select items.
Best Buy: Member Deals 30% Off + 2% Cashback
Best Buy’s member-exclusive deals continue with 30% off or more on select tech, paired with a steady 2% cashback sitewide. The retailer’s sales event features up to 50% off select items, with TVs, laptops, headphones, and smart home devices remaining competitively priced. As we approach the fall tech launch season and Amazon’s Prime Big Deal Days, expect Best Buy to roll out competitive counter-promotions in the coming weeks. The open-box and certified refurbished sections offer additional savings on returned and display models. With cashback at 2% on this channel, it’s worth comparing total savings against Amazon and Target before purchasing tech. All major appliances ship for free, and many items are available for same-day in-store pickup. Check the deals section for weekly-exclusive offers on gaming, home theater, and computing products.
eBay: Late-September Flash Deals + Certified Refurbished Value
eBay’s late-September flash deals continue to deliver deep discounts across electronics, fashion, home goods, and tools. Certified refurbished electronics remain one of the best value plays for budget shoppers, and auction-style listings can yield unexpected bargains as sellers clear out remaining summer inventory. Many items ship for free, and CashbackIndex users earn rebates on all eligible eBay purchases. As we move further into fall and toward the holiday shopping season, watch for rotating flash deals on outdoor equipment, patio furniture, and summer clearance items that retailers are eager to move before holiday inventory arrives. eBay’s buyer protection program and free shipping on many items make it a safe and convenient option. Check the daily deals section for rotating discounts across categories, and look for seller-sponsored coupons on high-demand items.
