what happens when paypal overdrafts a checking account (with an ample backup funding source available)?

you should check directly with the seller. i suspect you will find they have not recieved any money. paypal tend to hang on to money as long as possible in all transactions, and will do anything to avoid giving out cash before it has come in.
