If you are in no hurry to get your gears, don't mind grey sets if the price is lower, I can say go for it. Of course you need to know what you want to buy. They deliver to you without charge.
I got my 2 gears during the x'mas and CNY festive season. The first purchase only came about 9 days' time, and I'm still waiting for my second which is already 10 days. Be prepared for longer delivery time though they said most items will reach you in 5 days' time.
