Haven't you learned yet that there is no free lunch? There is no quick way to make a buck. If there was, everyone would be doing it.

Regarding importing from China, if you pay crap. expect crap in return. Expect one out of every three items to fail. You will spend a great deal of time, money and effort dealing with returns from customers and you won't be able to send defective items back to China for a refund.

Yes, I've gone down that path. Never again.
