I have much better luck on aliexpress than on ebay lately. Some sellers on aliexpress has no stock, and use that as an door opener. You at least get back the money if you do not "accept" and the benefits of doubts go to the buyers mostly. The exchange rate lost that is the problem created by the bankers, not Aliexpress or sellers. I see it as a necessary friction. Once the seller build up the ratings, they would do many things to protect their ratings. I was offered refund for events later I found to be my problem. And some sellers do not intend to make money at the beginning, and even run them at a small loss to build rating. But always always check and check, and test very well and long, and accept after the burn in. File immediately if in doubts. On ebay, I was cheated more by ebay on the money back protection scheme than the seller. Because one of the sellers who has a 99% know all the trick to drag and to trick buyers into not able to file or win claims.
I think these China stock if real shall appear on Taobao soon. Those available now on Taobao are imported stock as they are about SGP price. I shall keep the forum inform. It is a paradise on Taobao if you know how to shop. They have many levels to protect the buyers, and the sellers normally run around in the day, and do customer service till 1-2am, and if they do not get Full Positive, they shall offer refund immediately even the fault is not theirs. Of course, some school fees needed to be paid at the beginning but it is worth it.
