I buy from them and resale on eBay and Amazon, i get round 2 deliveries from them per week.
If you are thinking of doing the same my advice is DONT spend over $50 at anyone time, customs are more likely to stop it and charge you duty, I spend $25 2 or 3 times a week which keeps it under the customes radar, also items take between 15 - 30 days to get to you, and they are always celebrating some kind of public holiday which slows it down even more, eg last week they had 3 days off for some Moon holiday lol
Cheers
