remember, Aliexpress will protect you if you use their billing and processing system. Otherwise, you are NOT protected if you decide to pay via paypal outside of their automated system. They are not able to hold the money until you received the product. You'll have to dispute any issues with paypal. And if seller provides tracking information, then the buyer is out of luck.

you should email Aliexpress customer service to confirm if paypal is okay.
so sounds like its better to go thru aliexpress? what made some of you guys decide to use paypal instead?
