Walmart: Up to 60% Off Back-to-School + 8% Cashback on Select Categories
Walmart’s back-to-school sale continues strong this week with up to 60% off on supplies, apparel, and dorm essentials.

Best Buy: Member-Exclusive 30%+ Off + 3% Cashback
Best Buy is pushing member-only deals hard this midweek, with 30% off or more on select tech for My Best Buy members, plus a steady 3% cashback on all online purchases. The retailer is also running up to 50% off in its clearance section, and Shark and Ninja products are seeing elevated rebate rates up to 12% through partner portals. If you’re shopping for a new laptop, tablet, or dorm-room TV, now is a solid window before late-August inventory tightens.

Amazon: Daily Deals Up to 50% Off
Amazon’s August daily deals are delivering up to 50% off across electronics, home goods, and fashion, with 50 verified offers active as of this week. Prime members get early access to lightning deals, and back-to-school categories like laptops, backpacks, and calculators are seeing some of the season’s lowest prices. While Amazon’s direct cashback rates fluctuate, shopping through CashbackIndex ensures you never miss available rebates on Amazon purchases.
Macy’s: Flash Sales Up to 70% Off + 4% Cashback
Macy’s is running midweek flash sales with markdowns up to 70% off in select departments, alongside a back-to-school promotion offering up to 50% off. Use the current home-items code for an extra 15% or 10% off (valid through August 14), and earn 4% cashback sitewide through CashbackIndex. This is a strong window for dorm bedding, bath essentials, and casual campus apparel.
eBay: 20% Off Back-to-School Sale + Spotlight Deals Up to 70% Off
eBay’s back-to-school promotion is still active with code FIRSTBELL20 for 20% off eligible items, and Spotlight Deals are hitting up to 70% off with free shipping. App users can clip an extra $10 off $50+ with code YUSPGIXNWN7SZGCM. All eBay purchases earn 1% cashback through CashbackIndex, and certified refurbished electronics remain one of the best value plays for budget-conscious students.
Bonus Pick: Lenovo – Up to $100 Off + 5% Cashback
For students shopping directly for laptops, Lenovo is offering up to $100 off with code BUYMORELENOVO, up to 30% off sitewide, and a competitive 5% cashback rate. Student and educator discounts stack with these offers for even deeper savings on ThinkPad and IdeaPad models.
⏰ Time-Sensitive Reminders

- eBay’s FIRSTBELL20 code is back-to-school seasonal and won’t last into September.
- Walmart’s 8% cashback boost on beauty and apparel is a limited-time rate – lock it in now.
- Target’s 60% off supplies sale runs through August 31, but popular items sell out fast.
