I literally HATE PAYPAL and could write a book why. Use anything else.

USPS money orders are protected by the US and a Federal crime to fake. The special protections inherent with using USPS money orders made them a favorite in my early eBay sales and I still use them.
Funny story; paid a friend with one recently and he asked me what it was (He is a Postal Worker).

Good point. Carrying large amounts of cash around is unpopular with younger people. Some wouldn't even consider the concept.
I have "Rode Shotgun" for many friends conducting cash transactions (all legal). It's real.
I see desirable machines in Northern Cities I'm not familiar with at great prices.
Then I contemplate driving up there with a wad of cash to get a deal.
Right.
I resist using paypal at all costs. I also ain't going to a high crime city with a wad of cash, where my "shotgun" is illegal.
This is the primary reason I don't have a larger collection. All the good machines at fair prices are everywhere but near by.

No
