Torture for an Italian girl

I just returned from doing the bulk of my shopping, at Walgreen's of all places! I already did some shopping at Dave's, but after scouring the Sunday ads, found that WG's had some good deals. My current tactic for this challenge is going to be to make good food a la Grandma -- and eat the same thing every day. This replaces my original plan which involved a lot of mac and cheese and Ramen noodles. This change was made possible by my rock-star find: Buy One, Get One Free Pot Roast at Giant Eagle! Hello, crock pot!

So, this is what I got for my money:

Jif CREAMY Peanut Butter (eat your heart out, Ann!) $1.67
Smuckers Jelly (which I may not use) $1.67
Brownberry Bread $1.98
Whole Wheat Pasta (1-lb) $1.00 (it was 2/$3 and I had a 50 cent 0ff coupon that they doubled at Dave's)
Red Potatoes (5-lb bag) $2.99
Carrots (1-lb bag) $0.89
Oatmeal $1.40
eggs $1.50/dozen
milk $2.99/gallon
chicken stock $1.99/carton
egg noodles $1.00
pot roast $5.53 ($11.06, BOGO...I froze the other one)

OK, so technically, I spent $24.61, but I'm not going to eat the entire jar of PB or the bottle of jelly. I'll only eat half the pasta and egg noodles at most. I won't use all of the potatoes, milk or eggs, either. So, according to the cost-per-serving calculations I did on Excel (yes, I'm a geek), I will only consume $16.70 worth of the food this week. I don't think that's cheating. My thought was that (1) if I was cooking for a family, there would be more people eating, so it would make sense to cook/buy in larger quantities, and (2) nothing here is immediately perishable, so it is likely that the individual or family would have some items left over from the previous week , or that could be used the following week (like PBJ, pasta, eggs, even milk).

More to add later, but it's time for our meeting!
