I went to Hong Kong last year. and they limit each person to only purchase 2 of each items. i wanna buy 3 wristbands, 1 for myself, 2 for my friends, they refused. Ended up i have to ask some stranger to buy the 3rd one for me. It kinda sucks. Yeah but the key is to queue earlier. then u will have a variety of goods for u to choose.
Hope this policy doesnt affect any other concerts locations..
