ICU• In Cart Upsell Cross Sell

This is a great app for a store that uses ajax carts! A lot of other popular apps out there do not work well with ajax carts so that was the main reason we tried In Cart Upsells out. So far it has worked great and was relatively easy to set up. The only reason it doesn't have 5 stars is I wish they had a chat for quicker responses for help, however, they do respond within an hour or two via email.
