Here's what I did. I opened a PP account, I opened a separate checking/savings account. When I have a build up of funds in PP, I send it to the checking. When it hits the checking I log into the bank and transfer it to a savings account.
It gives me a couple layers of protection, and there isn't enough in the PP account to lose sleep over, and the same with the checking.
Postal MO, is the next best option IMO. It protects you from getting a forged money order and it protects the buyer too. If you were to stiff them it's a federal crime and they WILL look into it.
Best thing I can suggest, is when you do a transaction with someone here, follow through quickly, keep the communication line open, send tracking numbers etc..
Once you have a couple of sales, and some folks leave you positive feedback it gets better.
