For people that have had bad experiences with Paypal have a look at http://www.paypalsucks.com/. I was quite amazed at the problems people had with Paypal’s methods.

They routinely shut down people’s accounts for minor things. It doesn’t seem to matter if you have thousands of transactions and are a loyal customer. It has been a while but it happened to me once. You are treated as a guilty low life. The appeal process is quite weird. Please form your own opiniion but I would not recommend leaving large balances in your account.
