I placed a few orders to one shop knife shop around the 15 & 17. I like them and have had good business experiences with them in the past. I live at a APO address so I wanted to confirm that it would be sent USPS instead of UPS. I sent them a few replys to the order confirmation addy and a few emails to listed addresses under the contact us and have had no response. Recently I sent 2 more and received a non delivery notice stating that the recipents mailbox accout has exceeded its size and my mail was returned. Something happen to them? The email I sent them was 2KB in size.
