Track a price
Paste the address of a product page. If it is something we already record — 263 products so far — you will get its price history in one click. If it is not, it goes into the queue we work through by hand.
Skip the pasting
Drag this to your bookmarks bar. On any retailer’s product page, click it and you land back here with the address already filled in.
It reads one thing — the address in your address bar — and sends it to this form. It cannot read the page, cannot see anything you type, and runs no code of ours on the retailer’s site. That is the whole of it:
javascript:void(location.href='https://basketprice.com/track?url='+encodeURIComponent(location.href))
Retailers we can watch
Amazon. A link to anywhere else cannot be accepted by the form: a new retailer means reading their robots.txt, learning where they publish a price and holding whatever licence covers it, and none of that is a decision a form can make.
What happens next
- Nothing is fetched when you submit. A person accepts the URL first, which is why this is not instant and why the form cannot be used to point our crawler at an arbitrary address.
- Once accepted, the price is checked every six hours like every other. The first verdict comes after ten recorded observations — before that the page says it does not know yet, rather than guessing.
- The record starts the day we start watching. We cannot show you what a product cost last Christmas if we were not recording it last Christmas, and we will not reconstruct one from a retailer’s own claims about its old prices.
