I ordered two service dog tags and the price included postage. They arrived but were not delivered to me because postage was due of $4.25. I emailed the owner, sent him a copy of the post office notice, but he refused to either call the post office or pay the postage. He kept insisting he had put enough postage on. So I had paid $78 for the tags but did not have them. The P. O. returned the packages to him and I had to battle through Paypal to get refunds but finally did. The owner apparently does not understand postage rules and thinks that because he uses a postage service, that guarantees everything. I tried to warn him that extra postage is also due if he put anything metal in an envelope instead of a box, but he still refused to do anything about the situation. He is not competent to be running an internet business that relies on the post office to deliver his merchandise.
