joe1225us....happened to me recently.
I tried to save a buyer $$ on postage on a shipment
to China....DUMB ME!
I figured I could send "certificate of mailing" which is
$1.30 + regular postage.
Certificate of mailing is a receipt from the PO that they
accepted the item to be mailed.
Well....you know what happens....
Buyer in China claims non-receipt.
BAM!! Money withdrew from PayPal....
refunded to buyer.
After escolating to claim.....I was denied because
I needed a signature for proof of delivery.
So...seems all this
ebay with tracking is no good if
buyer does not sign for it.
