This is a bit off topic, but the FAQs on your website recommend that people insure shipments of cash. As I understand it, UPS/USPS/Fedex will not insure cash or cash-like items. You should look into this so that you don't misguide your customers.
Thanks for the correction. I was at the UPS store the other day and this guy wanted to insure $10,000 in cash he was mailing to his nephew. He wanted to mail the cash to keep it off the record and out of the view of the IRS. The people working there said UPS and FedEx wouldn't insure cash. But, apparently the government will.
