🔉 Introducing the Combined Add-on and Main items in Cart and Checkout page!

We are thrilled to unveil a highly requested feature that many of our users have been waiting for - Combined Add-on! This powerful addition gives you, the Shopify merchant, the ability to stack the add-on items to the main product, reduce the quantity of add-on items displayed in the cart.

Using this feature, the add-on items and related main item will be combined into 1 item in cart and checkout page.

From the example we mentioned above:

All add-on items price will be calculated to the main item price ($19.99 + $10 +$10 + $10 = $49.99)
All add-on items will also be combined to the main related item into only one item in cart and checkout page.
