All my youth I wondered why there were people out there who ENJOYED shopping for clothes. Any time I went, it'd invariably get interrupted by sitting down for 10 minutes while they "check the back" before letting me know the stock manager doesn't think I exist.
Hell, if I order from the fucking UK I'll get a better price, a better fit, and from a website that makes sense. These people COULD be offering special orders on their sites, a tiny warning saying "hey, this'll arrive next week from when you order" or whatever. I can wait, it's fine. It's what the state alcohol monopoly store does, and it works out great. But they won't.
