Farabiulder adds group buying to your Shopify store. Customers create or join a group, invite friends, and everyone gets the discount when the group fills. Set the discount, group size, duration, and eligible products. Groups that don't fill auto-refund through Shopify Payments and Stripe. The storefront widget installs as an Online Store 2.0 theme block and adapts to your theme. Every purchase becomes a standard Shopify order with the discount as a visible line item.
