Games at Walmart are under lock and key, so you have to go and drag down an associate to get them, and Walmart customer service is complete ass. For the most part, that isn't the fault of the floor associates as Walmart stores are almost always understaffed. There is no "in and out" with Walmart. Plus, the big-box stores tend to carry a limited selection of video games compared to Gamestop.
Our games have a security case on them, that they can open at the register. If no one removes it, it will trigger an alarm when you leave.
Why not use a system like that? They appear quite difficult to forcefully open. Impossible without some sort of tool at least.
Are people in the US really bringing tools to the store to break them inside the store? And so frequently that it becomes a problem?
I've never even heard of anyone ever doing that here.
As for limited selection of games compared to Gamestop, that's probably the case here as well.
But if it's a new game, they'll have it. So I mentioned it since Shadow said he likes to buy them early, or day 1.
