Seller cancelled order citing something wrong with buyer's mailing address. I receive many order daily from USPS/UPS/FedEx from Ebay sellers all over the USA and sometimes from other countries. I don't understand this sudden cancellation. This has caused a hardship for me and my customer as these were sold. You would think that a very basic measure of courtesy would be extended before cancelling an order. I would like to give positive feedback, but this seller has not earned it.
