How it works

  1. 1

    We pull a year of prices

    We fetch every price change for this product over the last year, new from Amazon or any seller.

  2. 2

    AI reads the history

    Our AI, a decision model running on Cloudflare, weighs today's price against what it usually sells for, its lowest in a year, and any rise just before the "deal".

  3. 3

    You get the verdict

    Bad, OK, Good or Great, with the reason, and a warning when a discount was made by pushing the price up first.

It judges the price only, not the product. Prices change fast, so check the store before you buy.
