Amazon shows "-36%". Against what? Usually against a list price almost nobody paid. This Actor checks each product's price today against its own price history, rebuilt from the copies of the product page kept by the Internet Archive, and gives one verdict per product:
| Verdict | Meaning |
|---|---|
real_deal | Today's price is at or under the lowest archived price (within 2 %). |
good_price | At least 10 % under the product's average archived price. |
usual_price | Within 10 % of its average. The "discount" is the normal price. |
above_usual | More than 10 % over its average. Wait. |
not_enough_history | Fewer than 3 archived prices. Delivered, not charged. |
Give it searches ("robot vacuum") or ASINs, and it returns one row per product with today's price, the discount Amazon claims, the real discount against the average, the historic low with its date, the high, the average, how many archived prices it saw, and the price in your last run.

Where the history comes from, and its limits
The Internet Archive keeps copies of Amazon product pages taken at irregular dates. Popular products have a copy most months going back years (measured on 40 well-known products: median 30 months of prices); a new or obscure product may have one copy or none. The verdict says how many archived prices it rests on (historyMonths); with fewer than 3 there is no verdict. The average is the average of those copies, not of every day in between.
Today's data is read from amazon.com without login or proxy; Amazon refuses some requests with a robot check, and the Actor retries and reports what it could not read. No reviews are read.
Schedule it
Run it daily on the same searches with the same stateStoreName and each row also tells you the price in the previous run and whether the product is new to the search. Turn on onlyDeals to get only what is worth looking at.
