EG gives you the power to cross-sell related items when a customer adds a particular product or collection item to the cart. You can target specific products to be offered with any cart addition with the fully customisable EG popup. Your customers can then add more products to the cart with just one click.
Recommending related products will encourage your customers to spend more and in turn, increase your average order value. A customer just added a winter coat to their cart… Why not recommend a range of gloves that match their new coat?
Follow these steps to create your own cross-selling campaign using EG:
Open the EG app from the Shopify admin page.
Create a new rule and name it appropriately.
Set the rule trigger you want to use.
In the rule action section, select Show a popup. This action is available on paid plans.

Select the products you want to offer to the customer when the rule is triggered. The Standard plan allows up to 6 products per popup, and the Unlimited plan allows more.

Configure the contents of the popup shown to the customer. Write an engaging headline and sub-headline to tempt your customer to buy more.
You can show or hide the prices of the offered products.

Apply other settings for the rule such as schedules, magic links etc.
Save the rule.
