Welcome to the Midweek Cashback Deals Update for September 30, 2026, brought to you by CashbackIndex. We’re now in the final countdown to two major shopping events: Amazon’s Prime Big Deal Days (October 6–7) and Walmart’s “Huge Deals Drop” (October 5). Early deals are already live, and Macy’s Star Member 20% off promotion ends in just two days. Here’s everything you need to know about this week’s flash deals, expiring promotions, and cashback rate updates.
Amazon: Prime Big Deal Days in 6 Days – Early Deals Include Free Kindle Unlimited & Audible Credit
Countdown alert: Amazon’s Prime Big Deal Days is just six days away (October 6–7), and early deals are already live for Prime members. Standout pre-event offers include 3 months of Kindle Unlimited for free, 4 months of Audible plus a $20 credit for free, and anti-aging skincare for $0. Prime members can also save $20 on Grubhub+ orders of $30 or more (7 days left). The full event will feature 48 hours of exclusive deals across more than 35 categories, with new deals dropping three times daily through Today’s Big Deals. Confirmed participating brands include Fisher-Price toys, Hunter boots, poppi beverages, and Phlur fragrances. Early Prime Big Deal Days discounts are already reaching up to 75% off in some categories. This is the perfect time to build your wishlist, set deal alerts via Alexa for Shopping, and make sure your Prime membership is active. Prime members get early access to lightning deals and free two-day shipping. Always start at CashbackIndex before shopping Amazon to capture available cashback rebates.
Walmart: “Huge Deals Drop” October 5 – Smart Home Deals Up to 65% Off Now
Walmart’s teased “Huge Deals Drop On 10/5 At 12AM ET” is now just five days away, likely timed to compete directly with Amazon’s Prime Big Deal Days. Ahead of the event, Walmart is offering up to 65% off on hundreds of Smart Home and Networking deals. Standout current deals include the Acer Nitro 34″ UWQHD Curved Gaming Monitor at just $189 (down from $250 – a $61 all-time low), and a Whirlpool 25 cu.ft. side-by-side refrigerator at a steep discount. Promo codes RAMPUP3 (15% off) and WELCOME20 (20% off) remain active for eligible shoppers. Note that Walmart’s cashback remains at 1% this week, so the value proposition continues to lean heavily on discount codes and direct price cuts rather than rebates. Walmart+ members enjoy free shipping with no minimum, while free shipping kicks in at $35 for everyone else. Mark your calendars for October 5 – this is expected to be Walmart’s biggest fall event of the season.
Macy’s: Star Members 20% Off Ends October 2 – Only 2 Days Left!
Urgent reminder: Macy’s Star Members Exclusive 20% off select items promotion ends October 2 – that’s only two days away. If you’re a Star Rewards member, now is the time to use this discount before it expires. Macy’s standard 4% cashback continues through November 1. Additional current promotions include 30% off Estée Lauder foundation and concealer, $20 in Star Money for every $100 spent, and $40 in Star Money for purchases of $150 or more. The sale section features Stuhrling watches at 50% off and Polo Ralph Lauren boys’ polo shirts at limited-time special prices. While the Best of the Season Sale has ended, Macy’s is expected to announce a Friends & Family event later in October, which typically offers similar savings. Star Rewards members get free shipping on orders of $25 or more with their Macy’s card. Start every Macy’s order through CashbackIndex to lock in the 4% cashback on top of these discounts.

The open-box and certified refurbished sections offer additional savings on returned and display models. All major appliances ship for free, and many items are available for same-day in-store pickup.
Target: 25% Off Select Continues + Halloween Season Arrives + 2% Cashback
Target’s popular 25% off select items promotion continues, valid through January 1, 2027. A separate 25% off select items deal runs through October 16. As October begins, Target is fully stocked with Halloween costumes, decorations, candy, and party supplies – many at introductory discounts. Target Circle Deals continue to offer up to $20 off select items, and Target’s steady 2% cashback sitewide continues through November 1. Target Circle Card holders save an automatic 5% on every purchase, and Circle members earn an additional 1% back in rewards.

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.
eBay: Pre-Event Flash Deals + Certified Refurbished Value
eBay is ramping up its flash deals ahead of next week’s major shopping events, with 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. Many items ship for free, and CashbackIndex users earn rebates on all eligible eBay purchases. As we approach Prime Big Deal Days (October 6–7) and Walmart’s October 5 event, expect eBay to roll out competitive counter-promotions on tech, home, and fashion. 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, and look for seller-sponsored coupons on high-demand items. This is a great week to compare prices across platforms before the big events kick off.

The most urgent deadline is Macy’s Star Members 20% off, which ends in just two days on October 2. The smart play this week: grab Macy’s 20% off before it expires, take advantage of pre-event deals at Amazon and Walmart, and build your wishlist for next week’s big events. Remember that Walmart’s cashback remains at 1%, so prioritize their discount codes and direct price cuts over rebate expectations. As always, the key is to compare total savings (discount + cashback + loyalty rewards) across retailers before buying, and to start every shopping session at CashbackIndex to ensure you’re getting the best available rebate.
