Co-Op Shopper Grocery Share
Split Costco groceries, track shares, and settle costs—automatically.
Bulk groceries are cheaper. Coordinating them across multiple people is not.
Co-Op Shopper Grocery Share Calculator lets groups plan a shared bulk order, split items and costs in advance, and—when working with a participating pro shopper—receive items pre-sorted into share-ready packages before delivery.
Who Grocery Share Is For

Grocery Share is built for groups that want bulk savings without bulk confusion:
-
Roommates sharing household staples
-
Families coordinating weekly or monthly grocery runs
-
Travel groups stocking up before arrival
-
Office teams sharing breakroom groceries
-
Neighbors combining select bulk items
If more than one person is paying, Grocery Share keeps it fair and clean.
Create a group and set sharing rules

Create a group and define how items are handled:
-
Even splits for shared household items
-
Per-person quantities for snacks, drinks, or toiletries
-
Custom shares when needs differ
What Grocery Share Does
Add bulk items once—then split them precisely

Add bulk and multipack items to a shared list, then split by:
-
Individual units
-
Sub-packs from multipacks
-
Custom quantity allocations
Automatic cost calculations

What is calculated automatically:
-
Individual item totals entered by each participant
-
Per-person subtotals
-
Estimated sales tax, delivery, service, and tip fees allocated proportionally based on each person’s share of the total order
No spreadsheets. No back-and-forth math. Just clear totals based on what each person commits to.
Cost Calculation Transparency
Each participant controls their own costs by selecting the items and quantities they intend to pay for.
The Grocery Share Calculator does not assume or auto-assign portions of leftover or shared items. Any redistribution of items must be coordinated within the group and, if needed, documented using item notes.
This approach ensures:
-
No assumptions
-
No forced allocations
-
Clear accountability for every dollar charged

How Group Ordering Works
A simple, streamlined structure keeps everyone organized:

1. Create or Join a Group
Set up a private group on my website or join an existing group hosted by your office, property manager, church group, or neighborhood.
2. Add Items to the Shared List
Each member adds what they want. The system keeps the list clean and easy to follow.
3. Finalize the Order Window
Choose a schedule. One combined trip reduces cost and minimizes congestion at checkout.
4. Delivery
Delivery for group orders must go to a single designated location—no split-drop deliveries.
5. Everyone Pays Their Share
The receipt is included with the order, and divided by household. Fees and markups follow the standard tiered structure.
