I would suggest only selling to members with high-trust when accepting paypal as payment.
You can be scammed even if you use an Escrow. Paypal transactions are reversible up to 180 days.
Its only 6$ im not worried.
If your happy loosing $6 its better for you to send that $6 to a non-profit organization or donate it.
There is almost 90% chance of getting scammed when using paypal.
I'm not an idiot. I know who to deal with. I doubt i will get scammed. Also nobody bothers to chargeback for such an amount.
