Goodbye paypal!

Another good practice is to have multiple paypal accounts. Since you can get multiple prepaid cards, you can open multiple accounts. Once funds accepted, move them away ASAP with "send to friends and family" option.
If there's a trouble with paypal transaction and paypal will try to hold on to your funds, they're not there. They can also set your account negative -- in this case you can easily send them to go suck their own sausage deep-throat and use one available to receive funds if sell anything. 

Remember they can uck seller HARD, but you can as well in response.

Go back to the old ways of business transactions;
Cash, Check or Money Order.

+ Bank Transfer with attached reference/proof to sale in question 

I prefer the old ways in many things :)
Czarivey, thanks for the prepaid credit card idea, it´s brilliant, as well
