How group buying works
- Reserve. Pick a product and the group you want to join, and reserve the quantity you need. Nothing is charged when you reserve.
- The group fills. Each group has a target size. When enough people have reserved, the group is full and the order goes to the supplier at the group rate.
- Pay. You pay for your share by the pay-by date shown on your reservation, by card online or as arranged.
- Pick up or have it brought to you. Choose free pickup, or have it brought to your postal code where the store offers that.
