Amazon: Prime Big Deal Days Officially October 6–7 – Early Deals Live Now
Mark your calendars: Amazon has officially confirmed Prime Big Deal Days 2026 for October 6–7, with 48 hours of exclusive deals across more than 35 categories. New deals will drop three times daily through Today’s Big Deals across beauty, tech, kitchen, fashion, and more. Prime members can also use Alexa for Shopping to get notified when deals go live, helping them grab items before they sell out. Early deals are already live with discounts reaching up to 75% off in some categories. Standout current deals include Rainbow Scratch Paper Sets at 50% off with code 11QJOXSC, and Dream Pairs Women’s Nia Sneakers as low as $14.84 with code 7TWJIT1Q.

Walmart: New Codes RAMPUP3 15% Off + WELCOME20 20% Off
Walmart has refreshed its promo code lineup this week with RAMPUP3 for 15% off and the returning WELCOME20 for 20% off at checkout. A $20 off eligible orders promotion has about four days left, and code X7EFM62H offers up to 68% off select items. Walmart+ members can now earn up to 5% Walmart Cash on hotel bookings, vacation packages, car rentals, tours, and activities through Walmart+ Travel (powered by Expedia). Note that Walmart’s cashback remains at 1% this week, 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.
Best Buy: Dash Cam Sale Up to 60% Off + 30% Member Deals + 2% Cashback
Best Buy is running a major dash cam sale this week with discounts of up to 60% off on models from Rexing, Vantrue, Viofo, and Redtiger. Standout deals include the Redtiger 4K/2.5K dash cam at just $84 (down from a comparable value of $210), and the Viofo A329 at a steep discount. Prices range from about $76 to $430, with free shipping on most models. Beyond dash cams, Best Buy’s member-exclusive deals continue with 30% off or more on select tech, paired with a steady 2% cashback sitewide. Additional promotions include 10% off select appliances with coupon and 20% off or more with the Best Buy credit card. With 50 verified offers active as of September 29, Best Buy remains a strong destination for tech, appliances, and electronics. The open-box and certified refurbished sections offer additional savings on returned and display models. As Amazon’s Prime Big Deal Days approach next week, expect Best Buy to roll out competitive counter-promotions. All major appliances ship for free, and many items are available for same-day in-store pickup.
Macy’s: Best of Season Sale Ends – Star Members Get 20% Off Select Through Oct 2
Macy’s flagship Best of the Season Sale ended on September 28, but the retailer isn’t slowing down. Star Rewards members can now enjoy 20% off select items through October 2. The Semi-Annual Suit Sale ended online on 9/28 but continues in-store through 9/29. Macy’s cashback has returned to the standard 4% sitewide (the elevated 5% rate was a temporary promotion tied to the Best of the Season Sale). The 4% cashback continues through November 1. While the big sale has ended, Macy’s still offers 25% off with text signup and ongoing clearance sections with deep discounts on fall fashion, outerwear, and home goods. Star Rewards members get free shipping on orders of $25 or more with their Macy’s card. If you missed the Best of the Season Sale, keep an eye out for the next Friends & Family event later in October, which typically offers similar savings. Start every Macy’s order through CashbackIndex to lock in the 4% cashback.
Target: 25% Off Select Continues + Snack Deals Rotate + 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. Some recent snack promotions have expired (BOGO 50% off Brach’s & Nerds candy, buy 2 for $7 Cheetos/Ruffles/Smartfood), but new weekly deals are already rotating in. Target Circle Deals continue to offer up to $20 off select items, and a $5 off promo code is available for eligible shoppers. 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. With fall in full swing, Target is a reliable destination for home décor, transitional apparel, Halloween supplies, 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.
eBay: Pre-Prime Big Deal Days Flash Deals + Certified Refurbished Value
eBay is ramping up its flash deals ahead of Amazon’s Prime Big Deal Days, 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. A standout deal this week is the reMarkable Paper Pro bundle at just $380 (or $342 for new accounts with code REMARKABLE) – the lowest price ever seen, down from $410 last month. Many items ship for free, and CashbackIndex users earn rebates on all eligible eBay purchases. As we approach Prime Big Deal Days on October 6–7, 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.

Macy’s Best of the Season Sale has ended, but Star Members can still save 20% on select items through October 2.
