Do not try and pay by PayPal w/o asking first

We are seeing a ton of people trying to use PayPal inappropriately by paying for an auction and then asking for the item to be shipped to another address other then the address on their account. We require the buyer to communicate first after an auction closes to ensure the are not trying to do something inappropriate. This is VERY confusing to a buyer when they go to pay and PayPal states yep you have paid for the auction when in fact they did not. This is a SERIOUS FLAW with PayPal but it is the only way to protect ourselves...sorry
