We have the oddest shopping and dining out patterns.
Both DH and I work outside the home. And we both have "don't really have to worry about money too much" kind of incomes. But I'm fairly frugal naturally and he is a spendthrift. Our kids are 4 and 5.
Since the kids were born, we buy most of our groceries from an internet based grocery delivery service (
www.simondelivers.com). We spend about $80 a week. But the kids get two meals five days a week at daycare, and DH and I eat all our lunches out - these tend to be the big meals of the day. DH doesn't get home most nights until after seven, so I feed the kids a lunch-like dinner - mac n cheese, peanut butter, chicken nuggets. I usually just have a snack (last night, fried tofu - night before peaches and cottage cheese) and finish off theirs.
Once a month or so we end up at the grocery store - either looking for things simondelivers doesn't carry, or because we missed our order or forgot something. We tend to spend more at the grocery store than when we shop over the internet. More browsing. For the most part, we shop pretty high end luxury markets - it adds about 15% to the grocery bill, but they bag and take your groceries out to the car for you - which is really important to me when I have two preschoolers along to watch in the parking lot. Also, the produce is better - simondelivers doesn't have great produce (you don't pick it yourself, so you don't get to decide if the plums are the right ripeness, and sometimes things are a little more bruised than I'd choose) - and the produce is really nice at the markets I shop at (so is the meat).
If I don't have kids along, I shop the discount grocer. I also do Sam's Club on occation - milk there is a dollar a gallon cheaper than I can get it anyplace else - and probably spend another $40 at Sam's Club over the course of the month (excluding gas, which is why I have a Sam's Club membership). I buy things like laundry detergent there or at Target.
We do a lot of dining out and pizza on the weekends.
