Propel Upsell & Cross‑sell , 251 reviews

it seems pretty good so far! seems a bit expensive for our particular uses, but it does what we were looking for, i think.

We tried a lot of app to upsell addon products. This one seems to work best for us. We had an issue after an update was made and the customer support was superb

Very simple and effective app for upsells. I had an issue showing ATC pop up for differents URLs (different product pages languages). Support was super reactive and fixed the issue real quick. I highly recommend!

I was extremely surprised to see the take-up rate. Easy to install and does the job very well! The revenue generated definitely makes this app worthwhile. This one is a keeper. :)

Awesome app, the free version is enough to get you started. It's just what I was looking for.
Thanks.

Great free plan, first time it was not working I re install the app and it work perfectly ! If I do sells I will definitly upgrade !!

This app was easy to set up and it works perfectly. I can't wait to see how it works for my store and customers.

The app is good for me. The free plan is also enough for my things. I had one time a little problem, the support was quickly and very friendly.

Great free plan and support! Super easy to implement and the support team was very responsive and helped me get set up right away.

Amazing support, they resolved all our requests quickly and successfully, helping the app work perfectly with our theme. Oh, and app has fantastic options and everything you need for creating upsells!
