Damn Ebay sellers!!!!!!!

[TwoTees]

I would assume the guy that bought the rear seat hinges got himself some bucket hinges. Here hoping he sends them back if it is the case.
I have sold stuff before and it could be an honest mistake. I alway print out the paypal or ebay invoice for each item and use that to write the name and address on the back and tape it to the parcel.

EDIT
If the the unfortunate happens and you only get a refund make sure you get your postage back too. If he says he will only refund item cost open a paypal dispute and you will get all your money. I've been there.
