"Ordering is generally easy but many sellers want you to have a PayPal account which is also easy to set up. You can tie it to your bank account for instant transfer or, as some have suggested, only put enough money in the Paypal account to cover the purchase you are about to do. This you'll do by computer too. Some sellers will take credit card number or even hold your purchase while waiting for your check."
Here's a tip. NEVER link your bank account to Paypal. Not because of fraud either... Paypal CAN FREEZE your paypal account during a dispute, and if your bank account is linked, it is frozen as well. I have never had this issue but if you google it you will find plenty that have. I use a debit card that is just for Paypal. Add the exact amount per purchase, and no issues. Happy Fleabaying...
