UpCart—Cart Drawer Cart Upsell

We were instantly pleased with the integration of quick checkout options (PayPal, Amazon and Apple Pay payment buttons); something many Cart Drawer applications don't provide. Unfortunately UpCart lacks in customisation options; specifically design and style. Almost perfect but still needs more work.

amazing app

Works well and definitely boosted conversions/AOV. Customer service is superb and very fast.
Would love to have a HTML section for "Above Upsell" to title the upsell.

The app and UI is very nice. Very easy to use and it does convert. The problem is, many times there is a 1-3 second delay in seeing the item in your cart. It makes me wonder how many sales are lost because of this issue. Hopefully they can solve the lag issue because I'm not sure it's worth the upsells if I'm losing sales altogether from the lag.

The response time was fast and they helped resolve our issue quickly. We had an issue with the cart that was resolved same day.

I have tried this , the ui is fantastic , no one can beat the ui , all three app made by this team are fantastic in terms of UI , but the reason I still cannot use this app is the little lag to come our cart when customer click add to cart. So, if they improve this I am going to add it :). You can definitely try this app.
