I notice that cash is getting fashionable again because of issues with credit card fraud and identity theft. Then there is slick advertising and contract scams where everyone wants to take your credit card number to sell you one thing, then ends up charging you for a bunch of ther stuff you did not really agree to but was implied somewhere in the contract.

A lot of private sellers on bigger ticket items on Craigslist now are saying "cash only". It's just too easy for someone to grab the merchandise on a credit transaction then reverse the charge when them and the merchandise are down the road.

What you don't seem to get much of (yet) is special lower "cash pricing" on very much stuff outside of some private sales. If I don't get a special cash deal, I whip out the discover card and build reward bonus points. There are advantages and disadvantages to that I notice, like ease of accounting and proof of ownership on stuff.
