Every price on this site is the one the store lists. Official stores charge that price at checkout. Marketplaces add a service fee there, and some payment methods add their own, which our prices do not include: on a marketplace, the checkout total is the one that counts. On a game's page, official stores are listed before marketplaces, each cheapest first.
We earn affiliate commission from most of these stores. Commission never changes the price you pay, and it is never an input to the order of the results. Steam and the Nintendo eShop pay us nothing, and we carry their prices as the official ones to compare against.
Prices are collected periodically and can move before you reach the store. The price shown at checkout is the one that counts.
