The shop sells AV8001 50ml at HK$560, same as yours but no minimum request, even 1 bottle is the same price. She even said, she only can lower a bit (I guess around $10 to $20) if we buy more.
do u want to try it? the experience is good when i tried av9001 (one bottle only), but it's so expensive compared with av8001. so this time i want to buy av8001. do u want to join in group purchase? have u asked the advice for the beauty shop? and u can ask someone to share with u
