Plus Checkout Upsell+Free Gift

I am very happy with the app:
* First of all, fantastic 24/7 support from Jaap and the team.
* Great overall coverage of upsell cases - from the cart to the checkout
* Intuitive admin UI

Highly recommend.

Jaap and the team are very supportive. They've already fixed my issue for now. However, the script by coding should be considered to change to a better set-up version so that we no need to use code anymore on both targeting product IDs or offer IDs.

Great support and extremely helpful, Shopremi.com absolutely recommends Upsellplus Checkout Upsell for anyone looking to convert more sales

Great, responsive team -- always willing to help troubleshoot and accept feedback! The app works well and in AB testing outperformed checkouts that did not have an upsell shown.

Jaap was always helpful and proactive helping us to set up the app across all our domains as our code base isn't easy to adapt to 3rd party apps. However, I believe out of the box UpsellPlus will meet many customers needs.

Great app for checkout and post purchase upsells. Works very well and doesn't bloat the storefront.

We were able to generate thousands of dollars of extra revenue thanks to this app.

best checkout app so far for Plus Merchants.
Jaap is also very patient and helpful!

very good custumer service, Jaap helped me with copying offers to other stores. will install in comming stores again.

Contacted Support and it was the Founder himself who helped us with our question regarding using the App. He was quick and very helpful. Also, the app is very easy to use and our issue was due to us not making sure that the item we had to upsell was in stock. All in all, great app and fantastic support.

A super responsive team -- willing to go above and beyond to ensure their app produces the results you want. Great working with Jaap so far!
