Fix product up-sell offer not replacing product
If you have setup an offer from the Up-Sell (Product) template and after the offered product is added to the cart the original product is still added to the cart follow the steps below.
In some cases the add to cart functionality is executed before the app has a chance to show the offer.
To make sure the app can show the offer before the add to cart functionality is executed,
add a DIV with the class "cl-cart-add" around your specific "Add to cart" button:
<div class="cl-cart-add"> <button type="submit" name="add">Add to cart</button> </div>
After you've completed this setup, the offer up-sell should replace the original product and only the offered product will be added to the cart.
If you need further assistance on the setup, please send us a request and we will be happy to help you out.
