How we compare prices
How we group products and put current prices in context.
One product, one page
Offers from different stores for the same model appear on one product page.
Price history
We chart our own price observations so you can see past changes and put a current discount in context.
Recorded prices and a store’s advertised discounts are different evidence. We identify the source of any comparison.
How does today’s price compare?
We compare the current price with our recorded history and show the figures behind the comparison.
