SellUp ‑ Upsell & Add ons

This App is really great BUT its not compatible with my theme (Booster Theme). It disables the Add to Cart button (its an important button, isn´t it ? ;-). I contacted the support theme of my theme and the support team of UpsellAp. There was nothing to do for the moment to fix that issue.
Hope they fix the issue one day and contact me to reinstall the app. Thanks.

This is a very good app with many possibilities to adjust. Also they provide a really good and powerful customer support. I can really recommend this app.

I had a minor issue with this app and my theme, reached the support and they responded right away. The issue was 100% solved. Thank you UpSell app, love this app!!!!

After what was an initial disappointment with the app, this was turned around quickly with a detailed explanation of how I could be helped. Whilst the app isn't quite what I am needing for my store right now, I am impressed with its simplicity and equally happy with the customer service. Bravo for persistence and not shying away from any difficulties.

This app is very easy to use and configure. It's nice that you can customize several pieces of not only the look/feel but also the content - you can over-ride the default text to make a strong call to action other than just Product Name.

We had a few quirky things in our theme that were not working quite right but Dan had them fixed in no time.

Highly recommend!

This extension has nice features and I have received great support. Plus I also like the minimalistic design.

App worked perfectly! Displays more products to buy with product customer is already looking for. Also upsells when add to cart is hit. Worked wonders for more products being grabbed during checkout. I 100% recommend SellUP! https://bluedirewolf.com

Issue after issue with this app. We were able to fix one thing and we found another problem that we need to deal with. Not sure if it's worth wasting the time.

Gran atención al cliente. Resolvieron todas nuestras dudas muy rápido. Su app es recomendable 100%.

I had some issues at first because of using a third-party theme but with prompt response was able to get it rolling
