Offering Free gift is one of the powerful feature of Checkout Boost which motivates customers to complete their shopping cart.
In order to get used of this feature, it is required that your product must have selectable options (Like Size or Color...). To add options to a product, click on the product from product list (STORE > Products). Under Product Options, click Add Options.
Use the dialog to create each of the different variations of your product. Once you've created your options, click Save. They now appear on the product page as individual SKUs (a SKU represents each individual option available for a product. If a product doesn't have options, then it has a single SKU).
Once you've created your options, you will be able to get use of Checkout Boost's free gift feature.
That's it :) Reach out to email@example.com if you need any further support.
