What's so special about postal money orders? Serious question. I'm not trying to cause a big ruckus. It seems many people really prefer the postal money order over some really easy forms of payment; head scratcher to me. I recently bought a rifle off GunBroker and the seller took only postal money order. I offered to wire funds directly to their bank but they preferred the postal money order. Why? Are that many people living without a checking/brokerage account? With so many easy ways to pay why postal money orders?
