I've grown to dislike MO's of late. Reason is I can deposit a check from my phone, but have to take MO's to the bank to deposit them.
Gary,
Don't feel alone. I had a letter stick to the bottom of a box, that instead of going to NH ended up in a small town in WY. Problem was it was a check to one of my suppliers, who gives 2% discount for net in 10 days. You would think letters and boxes would be kept separate, but I've watched boxes I shipped be dropped in one of those roll around bins many times, right on top of letters.
