01 Tracking and updating prices
We get product data directly from the official Amazon Product Advertising API (through the Amazon Creators programme). It's the same source Amazon itself uses to display prices on its site, so the information you see is the real one — not an estimate, not scraped data.
Products are updated automatically several times a day. The frequency depends on popularity and on when previous changes were detected: a product with a history of price changes is checked more often than a stable one.
02 How we calculate the historical low
A product's historical low is the lowest price we've recorded for that product since we started tracking it. Every time the price changes, we store it with a timestamp; that's what powers the evolution chart and the historical table you see on every product page.
Important: the historical low is calculated only over the period we've been tracking the product. If we added a product in March, we don't know what its price was in January. So products with a longer history have more reliable data. When you see the "historical low" tag on a product, it means the current price matches or beats the lowest we've recorded since we started tracking it.
03 How price-drop alerts work
On every product page you can set a price alert: you enter a target price and your email. When the product drops to that price (or below), we send you an email with a direct link to Amazon.
Alerts are free and don't require a password. We use magic-link sign-in: we send a one-time link to your email when you want to access your account, and one click gets you in. No passwords to remember.
04 Editorial policy and product selection
We combine two sources to decide which products to track:
- Editorial selection: we add products based on the categories real users care about and seasonal trends (Black Friday, summer sales, back-to-school, etc.).
- User submissions: anyone can add a product by pasting the Amazon URL. From that moment we track it like our own.
We do not accept sponsorships. No product is featured on the home page, in categories or in the "Top sellers" list because someone paid for it: the rankings reflect real data (largest discount, best historical price, most sold on Amazon, etc.).
05 Transparency: we are Amazon Associates
ThePriceMonkey participates in the Amazon Associates programme. This means that if you click one of our links and buy something on Amazon, we earn a small commission at no extra cost to you: you pay exactly the same price you'd pay going to Amazon directly.
That commission is what lets us keep the tool free and free of intrusive ads. We don't sell data, we don't insert third-party ads, we don't share your email. Affiliate links only.
