It is like ebay, ... there are different sellers - always be weary of the seller and look at his sales/feedback history. I have used it with success in the past.
This ^^^
Just make sure the seller has a good rating and more than 20 sales.
I pay with credit card and got my money back when seller was bogus.
I often buy at aliexpress , just do your homework with the seller and all should be Ok.
Guys, its not like eBay, at all!
AliExpress works by holding your money in escrow until you confirmed you've received the goods in good condition.
So the process is:
1. You buy the goods and pay with your credit card
2. AliExpress debits your account with the amount in question
3. The seller gets notified of your order
4. The seller ships your order.
5. You receive the goods and inspect it.
6. If for whatever reason you're unhappy, AliExpress will NOT pay the seller and you can asks them to refund you.
