My personal reviews on the different sources to obtain your 1/6s. Please note that these are just my personal review. In no way I am affiliated or associated to these shops. This article accounts for my experiences. I definitely encountered difficulties obtaining real reviews on these places, hence, my experiences.
TAOBAO (CHINESE PRODUCTS)
Taobao is currently one of my favorites. There are too many manufacturers originating from China. The brands I usually patronize, e.g. Hot Toys, Very Cool, VTS, Dam Toys, etc are from China. Hence, Taobao is one of the best places to look for 1/6 figurines. Note, I only purchase figurines from China. Items like apparels I will usually go to a local store so that I can try them on. I will also avoid pre-order items on Taobao, because I cannot predict if the sellers will actually disappear by the time the products are released. I cannot verify my statement, but given that preorders usually take 3 - 9 months to fulfill, I simply cannot overcome my obsessive behavior to check when the stocks will arrive. Preorder items are usually marked with a "订金" somewhere in the product description. However, I believe that I will soon give it a try since they usually collect just a very small fee ($10USD?).
An easy way to make sure that your seller is legit is to look for their sales review. I would try to stay away from getting affected by their rep points because I have heard that rep points can be doctored. However, I usually choose to buy an item using a few factors.
