growse, care to have a stab at this one?
Be more careful who you shop with and never use PayPal?

The "never use PayPal" is a good idea to be honest, company pretending to be a bank yet not having to follow any of the legislation. If you do use PayPal and you aren't very good with cash make sure you do not allow them to charge any cards or accounts, been a while since I went near them but I am pretty sure you can just have it as a funded account which you pay money in to?
