True Confessions

Non-food items are not groceries, right?  When we got groceries on Saturday, there were two items, totaling $3 that were not food.  Also, there was left $6.29 unspent.  today, i ran to the store (there's a reason i shouldn't do this) to pick up some things for a fun spring Break dinner.  My totalwas $8.51.  

I think I should add the $3 back to food budget since the needed items were technically not groceries.  Then,  I can cover the $8.51 I spent on sandwich stuff for tonight's dinner with this weeks $100. Or, I can fall back on the fact that we said we had $200 for 2 weeks, and I can deduct a few bucks from next week's shopping.  Which is the more honest way to go?
