I think a lot of sellers have figured out that cashing a postal money order at the post office leaves a minimal paper trail. Be hard for the tax man to pin down unless they deposit the money in the bank.
I had this thought too. Maybe people think the IRS can't track their "income" through postal money orders? If this is true, some may not understand just how much info the IRS have access to. They certainly have access to any/all accounts. The IRS also have a very broad interpretation of income, they even count credit card/airline reward miles as income now. . . . I suppose straight cash or barter is the best way to stay off the IRS radar?
