1st off all, you must know this site is meant to do business with Chinese only.(dont believe me? Go try now and keep Chinese english dictionary at yr side)
Every features in this site is made with intention to make buyers confuse and after you get blur and lost in transaction, yr money will be gone.
I dont know who manage this business, is it taobao staff or the seller. 1st you deal with taobao then if there is any prob. You will redirected to seller, and the seller will say "when did you buy from me?" (you are lucky if seller will even say that, in most case -NO REPLY).
