Consider also that you are paying for something you are not going to get elsewhere, at the same time you are shopping: You are paying for access to a shopping choice you CANNOT find outside of a convention hall, all in one place. For something like Gencon or Origins, this is definitely the case - but may not be the case for smaller conventions. Consider, at no other place anywhere in the country are you going to find EVERYONE's wares for sale, on display, physical product that can be examined, and available immediately. You can get these products and a similar breadth of choice online, but you cannot first examine them before purchase. So in essence, you are paying the con a premium for the shopping experience itself, which cannot be duplicated in the real world - no one has that kind of shelf space or selection as an RPG store. If a person finds the premium worth it, he or she will pay it. If not, they just won't go in. Either way, due to the nature of the shopping in a convention center, the vendors often barely break even at conventions; they do it for the publicity, and the exposure to their clientele which helps them get feedback.
