GiftPilot – Auto Gift for WooCommerce

GiftPilot lets you offer a free gift product to your customers. When a customer adds a product to their cart, the gift product you selected is automatically added with a price of zero. If the customer removes the gift manually, it is re-added on the next cart update.

You can optionally set a minimum cart subtotal. If set, the gift is only added when the cart subtotal reaches that amount; otherwise the gift is removed.
