Its inventories include new games, used games, new game accessories, old game accessories, and game magazines. Those inventories are divided into 3 ranks. Rank A includes the New games, Rank B includes the accessories and game magazines, and Rank C includes the used games and accessories. All those inventories come from different supply chain. The A ranked and B ranked inventory come directly from the game factories or the manufacturing companies which constantly supply and corporate with GameStop. The A ranked inventory is very limited. Each time GameStop only orders a very small amount of rank A inventory until they need more, then they have to predict how many more they need so they can order a certain number of that particular thing. Rank C inventories come from either customers or other game retail companies. Mostly GameStop would buy used games from customers who try to sell the games back to the store. Then the store will sell the games to other customers.
