Cartix Cart Discount + Upsell

A great app!!
The best features I liked about this app are as following:

The upsell section is very neat and the product presentation is very good.
The option to apply the discount code in the cart slider makes it easy for the customers to use discounts which helps with improving the conversion.
The app shows the translated names of the products when the store is visited from a different country than the primary domain.

Apart from that, the customer support is amazing!
