Monkeys BXGY — Buy X Get Y Free

Run Buy X Get Y promotions that give away exactly the items you choose. Free items are applied by a Shopify Function during cart and checkout calculation, so the storefront never decides a price.

• Target precisely. Collections, products, variants, or variant option values — with independent rules for what is bought and what is given away.
• Automatic or code. Apply in the cart with no customer action, or behind a discount code.
• Fails closed. A promotion whose configuration cannot be validated applies no discount, rather than matching everything.
