Don't Blow the Budget Now!

Going grocery shopping tonight with January's budget.  I'm starting the challenge early and plan to make the $80 last a few days longer than just January.  There are a lot of things on sale that I'll need to just fill in one ingredient we need here or there.  I added it up and it looks like the bill will come to about $50--EEK!  After tonight, though, I should only need milk for the last two weeks of the month and a few veggies here and there.  I'm just going to go for it!  Will update with the damage later.
