One bad thing about this selling technique, which might be effective in selling you stuff, is that right after walking out, you feel bad. You know you did not do the right choice and the probabilities of you walking again to buy more stuff from them or telling your friends how awesome these products are is so small, that they seem to aim to one-sell only. Maybe that's why they're so expensive: they know you're not going back for more. It's a cheap technique and it probably is not looking for anything long term... But in any case, you can always move to another mall or create a new crappy-good-looking product to scam more people.
