what's the most recent purchase you regret making?

Food.  Food is always a good idea in the short run, but ten buck here, six there, fifteen somewhere else, and soon, all my expendable income is gone.  And food isn't the type of thing you can use again and again.  One time use, and it's gone forever.  I've spent about $150.00 in the last 30 days on random food here and there. ... Think of all the other things that could've been spent on....
