Amazon Prime Day: the real cost-per-unit deals
Prime Day is Amazon’s biggest sale of the year — and also the easiest time to overpay for something dressed up as a deal. We don’t take Amazon’s word for it: every product below is ranked by its real cost per unit and checked against our own tracked price history, so you can tell a genuine Prime Day low from a marked-up "discount."
Prime Day usually runs for two days in mid-July, with a second "Prime Big Deal Days" event in October.
How to spot a fake Amazon Prime Day deal
- • A big red "% off" is measured against a list price Amazon sets — not what the item usually sells for.
- • Divide the price by the units in the pack. A "deal" on a small pack often loses to a plain big pack.
- • Check the price history: a real low sits at or near the cheapest we've ever tracked, not just a fresh strike-through.
