@Joe Nation,
I'm not exactly YOUNG but I'm not 70.
My husband isn't 70 yet chronologically but eventually he'll catch up to his inner age. (He's pretty much always been an old coot at heart.)
Anyway he pretty much refuses to do any commerce online. This isn't because of he's a technophobe, quite the opposite, he knows a ton about computers and handled computer security for his department at one point and did a lot of hacking as a diagnostic (to see where weaknesses were and patch them) and he just thinks it's all too easily hacked.
My position is, maybe, but it's not 1999 anymore and there are SO many people who do this stuff online that it would have to be that hackers would target us for some reason, and why?
Anyway, the point is that pretty much all of our bills are paid by check. Still. Now. Nearly 2013.
I use my checkbook occasionally for things where only cash or check are accepted (just got a Christmas tree with a check, 10% off of $45 is $31.50 sez the gal taking payments, did you say $40.50? sez I, no $31.50 sez she, um, OK), but those things are becoming more rare. (Never figured out the Christmas tree math -- that flyer said 10% off, I'm virtually certain, and I'm 100 certain the tree was supposed to be $45 original price.) (It's a lovely blue spruce. Nice and fat. Damn sharp though.)
