> The better question is why storefronts don't directly compete on price.
The way I see it, it depends how you see who is who's customer. Is the gamer the customer of the store, or are they the customer of the developer/publisher who put out the game, and in turn is the developer/publisher the customer of the store. The store cut is the price to buy their services, and they can shop around to find different offerings at different prices, just as gamers might be able to shop around and decide what (platform features) matters to them with the options available.
