Upcart—Cart Drawer Cart Upsell

Absolutely brilliant app. I'd had it installed for about 10 minutes and it already boosted the value of an order by £19 which otherwise wouldn't have happened. Excited to see the longer term impact. Very professional and clean looking, easy to use and the support from Pierre for customisations is instant and absolutely top class. Probably the best and fastest customer service I can remember experiencing to be honest. Definitely give it a shot. Easy 5 stars.
