Get the whole house adding to one shopping list

Help me set up a shared shopping list for our house.

Who's in the house: [e.g. me, partner, two teenagers]
Shop we use most: [e.g. a big supermarket, a local shop]
Things we buy most weeks: [list]
Things we often forget: [e.g. bin bags, batteries]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A starter list of our usual items, one per line, grouped in the order you'd walk round a typical shop (fruit and veg first, frozen last).
2. A separate "often forgotten" section at the end.
3. A short message for the house: how to add things and to tick them off in the shop.
4. A two-line rule for who adds what, so it doesn't turn into a wish list.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts. UK English.
