Amazon Prime Big Deal Days 2026 Deal Value Checker
The "original" or "was" price is set by the retailer and can be inflated before a sale. Comparing against a price you've actually seen recently — not just the listed discount — is a more reliable way to judge a deal. This tool runs entirely in your browser; nothing is saved or sent anywhere.
Free deal value checker built for Amazon Prime Big Deal Days (held October 6-7, 2026) and usable for any later sale — enter the listed price, the deal price, and what you've actually seen it for recently, and see whether the discount is real or just measured against an inflated 'original' price. No account, no browser extension, no product tracking setup.
How it works
- Enter the listed 'original' price and the current deal price
- Optionally enter what you've actually seen this item priced at recently
- See the displayed discount vs the real discount against your reference price — and a clear warning if the 'deal' isn't actually cheaper than what you've seen before
Frequently asked questions
When was Prime Big Deal Days 2026?
It ran October 6-7, 2026, starting at 12:01am PT on October 6. The sale is over, but this checker works the same way for any later sale, such as Black Friday or holiday deals.
Why do I need to enter a 'recent price' — isn't the listed discount enough?
The listed discount is calculated against Amazon's own 'was' price, which retailers set themselves and can inflate before a sale. Comparing the deal price to what you've actually seen the item cost recently is a more honest test of whether you're really saving money.
How is this different from price trackers like CamelCamelCamel or Keepa?
Those tools require finding the exact Amazon product page and tracking it (a browser extension or bookmarklet, sometimes a paid tier for full history). This is a manual, one-time check — type in the numbers you're seeing right now and get an instant answer, no setup or account needed.
What if I don't know a recent price?
The calculator still shows you the displayed discount off the listed price. Checking a free price-history tool for the specific item before buying is the more reliable way to know the 'original' price wasn't inflated.
