Upselling items is only available on our premium plan. Once upgraded adding upsell items is easy.
From the setting page find the Upsell Module section. Once found click the empty box or add product button.
A new window will pop up where you can select the product you wish to upsell. Once selected click the add button on the bottom right corner.
Repeat the process if you wish to additional items (max of five). Once complete toggle the enable checkbox and save your settings.
If a cart has multiple upsell items they will be displayed in a slider. You can reorder the items using the drag handles in table.
