My problems were in reference to the I won't ship statements, that I don't understand.So, just to confirm. You have seen problems, which could also be considered hassles.
My problems have been with USPS, UPS and FedEx. I have had things delivered to the wrong address, including a well marked Full Case of 9mms ammunition that the UPS was nice enough to carry into the garage of my next door neighbor, the 9 year old daughter couldn't carry it. Go with it, he forged my name to the receipt. He was fired and charged with Forgery, was arrested and promptly jumped back and hasn't been seen since.
That was the worst and is likely way it sticks out in my mind.
