I tried both Tao Bao and shops in HK. I ordered from a shop called fived, balloon a bit expensive but quality is good and all balloons are reusable. I bought 5 princess balloons and reused every year for bday, CNY night market, Christmas but my girl doesn\'t know it.
if need urgently, shop in HK is ok. i tried party for less and mr balloon, cant wxpedt much when u need it urgently, balloons cannot stand for 3 days, best quality balloon is in toysrus. the balloon was there unchanged for 3 years already.
