A little lesson learned.  I have been selling codes on ebay.  Their is someone else out there that has figured how to buy your points and then pay for the points and then have a dispute over the payment.  They end up winning the dispute because ebay will not verify confirmed shipment if the codes are emailed.  I would email the codes via "contact buyer".  So I thought there was proof of the shipment.  But, come to find out Shipment can not be verified unless it is actually sent by regular mail with a receipt.  The person who bought the codes then drops off the ebay buyers list as not being a active member and there is no way to even correspond with them.  This is a small lesson learned as the winning bids were just for $6.50 each.  If you don't want to be stung make sure you sent thru regular mail also.  Hope this save someone else.
