So far I've been under budget by $27.75 last week, and by $56.77 this week, see:
This trip I only needed four things: coffee, coffee filters, cat food and a roast that was on sale. And we're traveling this week for Christmas with Mr's family in Pennsylvania and therefore do not need $63.23 worth of groceries. So great job.
I did get some stuff to make more Jr food to bring along - rutabaga, anyone? - but that was the only legitimate impulse buy.
Shall we mark this one fail?
