You don't share an account — everyone gets their own sign-in, their own preferences, their own saved recipes. What you share is a household. Add the people you live with and you're working from the same lists, the same meal plan, and the same picture of what's actually in the kitchen. When someone uses the last of the coffee, it's gone for everyone, not just for them. No more standing in the aisle texting "do we need milk?" Households come with the one-time Ad-Free purchase and every subscription — two people on Ad-Free, three on Silver, five on Gold, ten on Platinum. The Free tier is a single-user account.

Three things that sound alike and do different jobs. Here's the short version: sharing is the action, a group is who you share with, and a household is the people you live with. Sharing is the thing you do to a list. Every list starts private — yours alone. Sharing it means handing it to a group of people who can then add to it, check things off, and see what everyone else has done. You can un-share it just as easily, and it goes back to being yours. Use it when you want a specific list in more than one pair of hands. A group is a named set of people that sticks around, and it shares lists — and only lists. Make one for your roommates, your running club, the four of you cooking Thanksgiving, your mother across town. Add people by name if they're already friends on Grocery List Plus, or invite them by email — they don't need to be a friend first. Build it once and you can hand it this week's list and next week's without rounding everyone up again. Everyone in a group keeps their own kitchen. Your inventory stays yours — what's in your cupboards, what you're running low on, what you bought last week. Nobody in a group can see any of it. They see the list you handed them, and nothing else. Use it when you want help with a list from people you don't live with. A household is the people you actually live with, and it shares everything. Not just the lists — the kitchen itself. What's in the cupboard, what's running low, what got used up yesterday, the meal plan, the whole picture. When someone finishes the coffee, it's finished for everyone. When someone's already at the store, they can see what the house needs rather than what one list says. Everyone in a household sees everything, and that's deliberate — a shared kitchen only works if everyone's looking at the same one. Household size depends on your plan: two on Ad-Free, three on Silver, five on Gold, ten on Platinum. Use it when you're running one kitchen together. And they stay separate. Being someone's friend doesn't put them in your groups. Being in your group doesn't put them in your kitchen. You decide each one, and you can undo any of them.

Yes — because it's genuinely one list, not copies passed back and forth. When someone adds bananas or checks off the milk, that's the list, for everyone on it. You'll see their changes when your list next loads. There's an activity feed on every shared list too, so you can see who added what and who already grabbed the thing you were about to go get.
