Excellent after installation support initially. After a recent update some of the more recent products were missing. Upsell support resolved the issue keeping me informed of their progress and it was all back and running smoothly in a couple of day. All in all an excellent App with support to match. Sept 2024 update - if an add-on goes out of stock it is still presented to the customer. This is a shame and something the developer isn't going to change (or make an option not to display) after enquiring with them.

We are facing the add to cart and discount related issues. Any one please let me know if you have any solution. We are using Maranello theme. 1. Add to cart count is not immediately updated in cart. Cart count is updated only after manual page refresh. 2. Discount price is showing in cart page but not showing in checkout page.

I am very happy with the Upsell Product Add-Ons app. I love that there are analytics so you can see exactly how many products and revenue has been generated by people using the Upsell App. The support staff was very helpful when I requested some changes with how things were displaying. I've been using this app for over a year now and can truly say that I would recommend it.

Very prompt and friendly customer support. Simple to understand even for me without any coding and programming background. Service our needs very well.

Customer support was prompt to reply and offer their assistance in the custom changes that we requested.

We use this to add accessory options to some products and it works well. Had an issue with the wrong currency showing but the support was very helpful and fixed it quickly.

This app works fantastic with Shopify. It is a great way to complement/upsell and also be used as a "discovery" platform for products. The support team is EXTREMELY helpful. This is one of our MUST HAVE Shopify apps!

We've only had the app installed for a short time, but so far we're really liking the presentation of the add-ons, and the customer service is top notch! I reached out with a question I thought was a long shot and they were able to help me with a solution very quickly. So far so good!

Support was outstanding! I'm amazed how they are helpful. If you face any problem or customization within the app - support will react ASAP and will help with everything.

Best app we have installed to increase sales! We have been using this app since we launched out site (5 months ago) and Add-Ons has been one of the most valuable apps we have installed. Average cart purchases have increased greatly, making it easy for customers to add items to their cart. The back end is easy to navigate, and the best part is that the developers will work with you to customize the look on your site so it matches your theme, which is invaluable. In addition, the developers are constantly trying to improve the app so new features are continuously pop up.

This app does exactly what I need it to do with ease and simplicity. The app has many options as to the appearance on the product page so it enhances my offerings. The customer service support I received was exceptional. I needed the app to allow for quantities and that feature was up and running almost immediately. Highly recommend.

Great value for money! I use this app to showcase a product in the cart, which is very easy to add to the basket just by clicking a button. I got very helpful support on setting up the app so the cart add-on blends very nicely in with my store theme. The customer service is very fast and helpful and open for suggestions to develop the app further.
