Good Good Study Be careful of buying stuff in this store, at least be careful of buy anything you are not sure about its quality, because the chances are you stuck with the poor quality stuff you bought. Apparently, this store changed its policy a while ago so that customers can only return unopened stuff. If you bought anything that was broken later, you may not be able to return it! I don't know how many things in this store are not allowed to return. This information is, unfortunately, never provided. An assumption is, if anything is not marked as returnable, it cannot be returned if you open the box.
Good Good Study I have been with this store for more than ten years. But, now ... Good Bye!
