Paypal is good for Buyers but sucks for Sellers. I've never had a problem with 5 years of using it untill last year. 2 guy within a month stuck me with a refund and kept the parts, paypal lets them get away with it. They will always side with the buyer on a dispute. But the kickers of it, think one was a 300.00 deal, they charged me 3% fee when I got paid, when they took the money back out they charged me 3% more instead of charging the jerk who was scamming me.
Another guy sent me a email telling me he'd send the product back if I paid him "more" money then he paid me. The guy wanted a extra $20-50.00 on a 65.00 part. I sent this to paypal and they still let the guy keep the money without sending me my parts. I use it but I am more careful with it now.
