[quote name='elessar123']As for gutted, if you don't like it, don't buy it. I don't, unless it's super cheap, or I'm buying to flip to Amazon or something.
I'm still pissed about their gutting my pre-order an hour after it got to the store, and also when I preordered 7-8 months in advance and didn't receive the pre-order item (Harvest Moon on Wii, gf has like every HM), because they said they ran out of the 10 they got in, when I went in an hour after they got their shipment. I went to another store a mile away and they had the pre-order cows and also previous pre-order Harvest Moon plushes left, and they asked if I wanted those. I only took the cow cause I felt guilty, but in hindsight, I should have gotten the other pre-orders too.[/QUOTE]
Your second paragraph in this quote explains the very reason why selling gutted copies pisses people off.
Also, other stores normally give customers a discount on opened merchandise. Those "new" games that GameStop sells gutted should be counted as "opened" and discounted. Otherwise, it's no longer new.
For a company that makes a helluva profit, they're extraordinarily cheap when it comes to ordering DVD cases to use for promotional boxes.
To answer the main question: It's because they've become the only major gaming retailer (yeah yeah, there's Game Crazy and Play n Trade, but they're not exactly everywhere in the US). They've bought out most of the competition and planted themselves in every location as if they were McDonald's or Starbucks. Not only that, but they've thoroughly convinced unknowing people that they're supposedly the only place to get games from and that if they don't pre-order certain games, they'll never find them for months. So they basically pop up everywhere like roaches to make traveling easier and quicker, while using scare tactics to get people to throw down money on unnecessary pre-orders.
