so the latest was a response to the paypal claim apologising but asking to send a blueprint and pics to a specific email address and they would respond on how they would fix it.  so tonight we recd a response via email (not paypal) for us to ship the item back and on receipt they will refund our shipping fee once we provided them with the receipt and they would then reship correct item. So I went into the pp dispute and basically copied what they had requested asking them if this was correct.  I did this so that I have proof in paypal.  once they respond I will send back item and keep my receipts for shipping so that if I have to prove to paypal I shipped I can do so.  Does this sound legit?  They are a power seller.  I just wanted to make sure that all this should be going via paypal to cover my end?
