Scams in dropshipping

Have you ever been scammed in dropshipping? I know of a person that makes some good money off it but just wanted to know what the rates were for being scammed. Please do tell us your stories below.

I have been scammed on:

Alibaba - I ordered 10 Alienware M18x Laptops, at some stupidly low price, I think it was $400 for each. The guy then never sent anything or replied. But he was stupid enough to use PayPal as his payment method, so I got my money back, and he got a nice letter sent to his house
