This guide very accurate because it is built using data from actual sales and listings across the internet. Prices are set by sale prices (with shipping costs included) and items listed with high rarity are that way because they have only appeared infrequently. This list becomes more accurate as time goes on!
The latest price is for items of all conditions and quality. Expect to pay more for games that are complete in the box.
