Fair point. We probably spend an additional $100/mo on paper goods, dog food, dishwasher detergent, etc., through Amazon Subscribe & Save because HT wants way too much or doesn't have what we buy. We already have Prime and it saves me both the extra trip to Walmart or Target
and whatever additional I might end up spending on stuff we don't really need. It varies a little but $600/month for the five of us (kids are 8, 6, and 5), plus the two dogs.
Weekly groceries for us is, typically, fresh meat, sandwich bread & tortillas, fresh fruits & veggies, graham crackers for kid snacks, cheese, eggs, and milk to last us the week. I choose meat and produce based on what's on sale. Most everything is HT store brand or whatever is cheaper by the unit price. I buy canned and frozen produce when it is on sale, extra bread to freeze if it's on sale, cereal/granola/oatmeal for kids' breakfasts when it's on sale, peanut butter & jelly (or make my own) and frozen pizza when it's on sale, and miscellaneous dairy when it's on sale. Milk for the week is at least 4 gallons of whole milk. If it's on sale, I might buy 4-5 gallons at a time.
We eat CFA or other fast-casual like Moe's or Five Guys *maybe* once a weekend, usually for lunch, and Chinese or Mexican is like every other month. Pizza delivery we do about once a month. That's probably $125-150/month.
@shawn eats out for most lunches because crazy work schedule but that's probably in the neighborhood of $60/week?
