Plus Checkout Upsell+Free Gift

Highly recommend this app, it's also the only app as far as I know where you can customize the upsell to the locale of the customer. Which we really need so we can add upsells in the local language. Also support is SuperB, best I ever had. They listen to feedback! Highly recommended!

Great App with a lot of features inside, very comfortable UI and amazing support, answering 24 hours a day!

The app is great to generate some extra revenue during checkout. It can be used without check extensions which was a necessity for us.
Jaap has been very helpful in setting it up properly.

Support is very effective! Those guys know what they are doing! Super great apps to use for Upsells and all!

Incredible app! Instant Return on investment. Highly customizable. The support is incredible. The app is constantly improving as well. super happy with this app!

This was a great app. Wish we would have found it earlier in our Shopify Plus experience. You can very easily insert upsells into liquid.checkout without having to actually code. And support was fantastic - they went the extra mile to help.

Amazing support. Great app and even better team. Highly recommended! If you need an app for cart and post-purchase upsell, this is the app for your business.

Great App and the customer support is by far the best we've ever had with any app integration. Thanks Jaap!

Excellent checkout integration. Simple UI. Amazing sets of options & rules. Incredibly responsive support. A++ as far as apps go.

Thank you dear Jaap and all Upsell Plus team for a great support.
Jaap was available all the time to support and handle some slight issues that came by. Also they made some app changes a specially for us.
