At the risk of sounding and getting a ton of hits and disappointing the pervs out there, I'm talking about the cashless,frictionless spending.
Frugality is all about the friction.
Seems like all of society is out there telling you "make it easy" and get with it, while are all here to say "stop for just a second" and "don't be a spending sheep" and "do you really, really need or want it, upon a few seconds of further consideration?"
Contrast cashless buying with layaway. Primitive, but that less than instant consumerism can give you a different way to demonstrate gratitude and compassion.
