About this block

Shared Cart is a collaborative cart built for a household: a contributors avatar strip sits under the heading, every line item names the person who added it with their avatar, and the summary splits the subtotal per person while a single card pays at checkout. A line under the list explains that anyone with the link can add or remove their own items, and removing someone else's pings them first so nothing disappears silently.

The layout is a two column grid, line items on the left and a sticky summary card on the right. Contributors and items are each an array, the item rows carrying an addedBy name and its matching avatar art. The summary footnote is clear that the per person amounts are for settling up later, the store does not split the charge.

When to use

Reach for this block when the cart genuinely persists across people and sessions, fed from a shared link or a household account. The per person split must reflect who added what, or the settle up math misleads the group.

What you can display

One strong use is the household grocery cart. Other shared configurations:

• Team supplies. A shared office cart where each desk adds its own items to one order.
• Trip planning. A group cart for a shared trip, split per traveler before booking.
• Registry pool. Several contributors funding items on one list, amounts tracked per person.

Tip: pinging before a removal is what keeps a shared cart calm, silent deletions turn a household tool into a source of small arguments.
