You do the math

I went grocery shopping today, 10% Tuesday. I walked to the store because it wasn't crazy cold out and I like the walk.

To get the 10% discount you have to spend a minimum of $25--excluding dairy (that's a weird condition I've never seen before but noticed tonight in the fine print). Before going to the check-out I estimated my grand total. I figured I had met the minimum requirement without going over too much. And I was right. My total was around $34.00. The other important calculation I forgot to take into consideration however, was weight.

I had amassed 2 kg of sugar, 1 lb of butter, 3 lbs of apples, 2 lbs of soup, and probably another 2 lbs of other random things that I hauled about four blocks home.

So when I got home, I felt no guilt about eating that leftover piece of cheesecake. Nope, none at all.
