OMG, I can't believe how expensive your food items are there.
I don't drink milk and the only thing we ever buy it for is my husband's cereal and he picks that up so I really don't know how much milk is.
As far as the other items, we probably would have to live on mac n cheese if we lived in Cal.
Here are a couple of examples~a loaf of bread is about 1.39 if you want a name brand loaf like Wonder Bread or something like that. You can get the store brand for about 99 cents. I'm hoping that I'm reading this part wrong. Did you really say a HALF gallon of ice cream is 6.00? It's about 2.59 here and cheaper when it's on sale. That would be a name brand like Land-o-Lakes or whatever.
On the steak question, I'm sort of at a loss.
I'm not much of a meat eater. But every Sat. night my husband BBQs a T-bone for himself. He loves steak and it's always WELL over a 1 pound package. I believe he pays in the area of 10.00 for it. I drink cherry coke in 24 oz. bottles. I pay 2.50 for a six pack of it, which is really reasonable. Eggs are about 1.00 a dozen. If you have any other questions, just list them and I'll check them when I go to the store this weekend.
