We have 2 adults and a 1 1/2 yr old in our house. We usually spend $200-$250 on groceries every two weeks, so it works out to be about $100-$125 a week for groceries. This includes all food, razors, diapers, and other misc items. For those of you that shop at Sam's Club or any other bulk store, how much do you really save based on how much spent per week. I have this general idea that we will spend about the same amout when we go grocery shopping, but will end up going less often. But also don't want to spend $400 per trip because you can buy only bulk and have to get a 1 gallon jar of pickles instead of something smaller.
Space is not an issue, I just don't have the money to spend $400 at once on groceries.
