GroupBuy adds a buy-with-a-friend discount to your product pages. A shopper starts a group, checks out at the group price and gets an invite link to share. If a friend buys the same product before the time limit, the group is complete and both keep the discount. If nobody joins in time, GroupBuy cancels or refunds the payment automatically. You choose the products, discount, group size and time limit. Discounts are standard Shopify codes used in your normal checkout.

• Invite links and deal timers on the product pages you choose
• Automatic refunds when a group doesn't fill in time
• Set the discount, group size and time limit for each product
