I can't deny what realtime said, however, there are several things to consider. I 've talked to many ppl they prefer paying extra for less traveling. Also, a lot of us doing this behind someone's back I assume, close to work, quick in-out, seamlessly as it just feels like a glitch during the commute.
Also manhattan locations mostly (not all) offers a nicer interior, some offer expensive alcoholic drinks (like PP/AS), big mirror for great viewing. so for people who's time = money, there are still merits.
remember the house rent in midtown is way higher than brooklyn/flushing as well, and in the cash chain we are the one paying for those else they go out of business. And trust me, alot of us don't want to go to super lower manhattan or brooklyn for one release...
not defending anything, and realtime is right on the price thing, just there is a reason behind that price.
