Another paypal lesson I learned recently was with regards to putting a deposit down on an item and then paying the balance when the item is ready to ship. Paypal only covers one of the transactions, usually the larger of the two or the balance, so if you put a deposit down and there is exhorbinant wait or you never receive the item at all and can't attain a refund, they do not cover the deposit amount, only the remaining balance amount, not both.
