Their tux rental service is damn near impeccable, though (at least here it is). We used them for our son's wedding, and you could not ask for better service.
Come to think of it, the few times I've bought there (maybe 5-6 times over the last 25 or so years), the service was always top-shelf. If you pay those prices and get good merchandise with that type of service, it seems like a fair enough deal, if not a particularly affordable one.
