In ShopDocs' Free Gift on Cart, you can set different purchase goals to trigger free gift offers. First, you need to select products that will be given for free. Next, you have to create gift goals and customize the appearance of the gift progress bar.
The gift offer will be shown in the cart, but you can also add it to any of your store’s pages to attract customers to spend more in order to get a free product. Besides a free product, you can set conditions for free shipping and discounts.
You can explore the app’s functionality for free only when your store is in a development mode. After you purchase a Shopify plan, you’ll have to pay for using ShopDocs' Free Gift on Cart as well. It costs $7.99 per month for Basic, Shopify, and Advanced merchants, and $19.99 for Shopify Plus. The latter includes priority support.
