You bring the game that you wish to buy to the cashier and you pay for it with money, in the form of a card, bills or change. The games come in a box, sometimes there is a booklet in the box, sometimes not. There is always a disc or a cartridge, though! You can put it in your console and play the game. You might also pay ~5$ less than at a retail store, but their selection of games is limited. You also need to exit the store once you are done if you wish to get home, same principle as you would find if you end up in a EbGames or a Futureshop.

really?... smh
I'm asking how limited it is. I remember a while back (6 months?) It wasn't as barren as it is now.
