Product Price Comparison
One product, every seller we can find, and the context you need to tell a good price from a low one.
One product, many names
The work in comparing a single product is deciding what counts as that product. The same headphones appear as a model number in one shop, a marketing name in another, and a bundle with a case in a third. Comparing the three as though they were identical produces a cheapest price that is not for the thing you wanted.
Listings are therefore matched into a canonical product first, using manufacturer identifiers where they are published. Each product page then shows the identifiers it has — brand, model, GTIN — so you can check the match yourself rather than take it on faith.
What each offer tells you
The landed total, the merchant and its trust score, stock status, condition, and a delivery estimate. Condition matters more than it is usually given credit for: a refurbished unit at a striking discount is a different product from a sealed one, and it is labelled rather than blended into the same list silently.
Every offer also carries the moment its price was read. Where a page is showing an older reading, it says so with the date attached instead of presenting it as current.
History, and what it is for
Each product page charts up to 90 days of prices with the all-time low and high we have recorded. A single price tells you what something costs; a line tells you whether that is a good moment to buy.
It is also the defence against a discount that is not one. A sticker cut from a price nobody ever paid looks generous until you can see the line it was cut from.

Search “Sony WH-1000XM5 black”Common questions
- How do you know the offers are for the same product?
- Manufacturer identifiers where shops publish them, and the title and attributes otherwise. Every product page lists the identifiers it holds so you can verify the match rather than trust it.
- Are used and refurbished offers mixed in with new ones?
- They are labelled with their condition rather than blended in silently, because a refurbished unit at a large discount is a different purchase from a sealed one.
- How far back does price history go?
- Up to 90 days, built from the prices recorded when the product was searched. A product searched rarely will have a sparser line than one searched often.
- Can I be told when a price falls?
- Yes. Set a target on any product and the price is re-checked on a schedule; you are emailed when the landed total actually drops below it, rather than when a shop announces a sale.
