The most unfrugal thing I did today was to spend on my computer setup.
Bought a new hard drive. OK, but the drive I bought is the biggest Ultra-ATA drive currently made for the PC. It uses the new vertical data storage technology that's just being released. And while I was spending, I bought a powered USB hub.
I will now go over to the "What frugal thing did you do today?" thread and post about buying both items on sale
and using a store gift card to defray part of the cost.
This dual posting is what's known as "buttering your bread on both sides without getting sticky fingers."
