I make a list as the week goes on. Its a large notecard in a place on the kitchen counter that hubby and teen daughter know where its at. I am constantly telling them to write what they want or need on it. I will plan some meals and seek the items in my very full cabinets and write what I actually need to the list as well. I actually write things in a certain spot on it. They have yet to determine any system to it, so it needs redoing before I acutally go shopping (It HAS to be right or I go bonkers...OCD behaviors? maybe? I think I just like what I like!). I am prepared when I go (but am not really a couponer).
I go to Sams Club, then Cub Foods every single Sunday Afternoon. If I need to make a run to Target, I do that first (maybe once a month). My Sams Club cart will have laundry supplies, paper towels and TP, cereal, crackers, canned things like diced tomatoes and some veggies, Splenda in the 1000 packet box, seasonings, gum for hubby, 90% ground beef, other beef, shredded cheese, yogurt, lots of fresh fruit/salad fixings and the light bread I like. Sometimes other stuff, but those are my staples I always buy there when I am about 2 weeks from running out. I ahve been spolied by a Saturday morning Farmers Market option for fresh veggies (mostly...sometimes fruits and other things) all summer but I think this might be the last weekend?)
Then to Cub to get the rest of my fresh produce, meat, some canned goods and smaller specific recipe items not available at Sams club.
I am a stock up person on many things so some weeks my carts are plum full at both places, and other weeks maybe half full. I always have to go shopping tho, as I always need bread and milk and fresh fruit. I do have enough stock, however, that if I am sick, etc, I can send hubby to just get milk, eggs and list a few fruit items specifically and he can get those and we can wing our way thru at least week.
When I bag the stuff, I have my own bags (altho I take their bags cuz I use them around my house for trash and recycle bags!). I put my cold stuff together, etc. Occasionally hubby comes with (like now as I have an injury) and he is like a ninja packer! He has it down to even more of a science than me (and can pack the bags heavier as he is stronger than I).
I do home childcare for 6 kids, plus my family of 3.
