There is one more slant on this. The buyer may have owed the seller $480 and this was a relatively inexpensive and convenient means of paying the debt. Not too many new sellers have PayPal accounts already set up. And, it may be the "buyer" had most of his available funds tied up in his PayPal account, so they conspired to transfer the money from one account to another with less expense than sending money directly from PayPal to an email address. There are a few twists which could be applied to the formula: the seller wanted to become familiar with
ebay and PayPal and a little positive feedback would help get him started.
It this is the instance, then actually it's pretty innovative.
