Nope, they need to change their entire store.Gamestop just needs to accept slimmer margins on their used games.
No way should I ever be able to buy a brand new game at Best Buy for cheaper than what it would cost used at Gamestop.
Amazon/Best Buy and others are most likely just breaking even or extremely thin margins on physical software these days. They use it to get people on the page/store in order to buy other things that are profitable. Gamestop cannot afford to do that since thats the bulk of their sales.
They need to adapt or they will die.
I actually think Gamestop is an important retailer for gaming, but they have had terrible management for decades.
