[quote name='TommyT53']I've had about 4 games canceled by Gohastings in the past 3 months so take it for what it's worth, but I refuse to ever shop with them again.[/QUOTE]
Without a doubt this can happen. If you realize how they fulfill orders, it becomes clear that it is more like a lottery with pretty good odds that you'll be able to get some games at really good prices, but sometimes not. But when buying used stuff from them, especially a popular or rare game, there is a good chance you won't get the item.
I only buy from them when I'm buying a single item at a great discount where I don't have to deal with a return if they can't fulfill the order, or when they are offering a free shipping deal where I'm not penalized if they can only fulfill part of my order. But I stay away from the "but 2 get 1 for $1" deals because it is too common that you don't get the deal because they only ship 1 or 2 of the 3 games you ordered...and usually neither of them is the $1 game.
But if you have a choice between GH and some other place for roughly the same price, I'd most likely choose the other place because they are more likely to be able to fulfill the order. But if they are offering a great deal, you don't really have much to lose by ordering from them because the worst case is you won't get it, but you won't have lost any money trying.
