For all you guys who did a paypal with your CC, SKIP THE PAYPAL DISPUTE, they will drag it out, until it's too late.
Instead send the item back, get a delivery confirmation number, call your CC company directly tell them the situation, and tell them you want to do a chargeback. They will immediately take it off your bill, and send you an affidavit to sign. Then THEY will contact paypal.
It's amazing how quickly things get starightened out with this method. Just don't do it for every little thing, only for big ticket items.
It is also helpful to provide them with the tracking number proving you already sent it back to the seller.
This is a a little known service you pay for via interest.
I had a member here, CPROBIKE, sell me a bad charger, I sent it back via USPS, he could not be contacted, I gave the CC company the tracking # and told them the situation.
He said he "was out of town"
Translation, the refund was forced, immediately.
I hope this helps.
