DiscountDuck quantity breaks

I downloaded it today, and it is great! Exactly what I was looking for, perfect for what I need it. Thank you!

A must-have app for your Shopify store. This app does what other similar apps don't do....it shows the discount in the shopping cart. Excellent customer service too!

Incredible support! Helped me with the install and loads of questions, and when I had some important feature suggestions the developer released a new update to the app within 24 hours!

App works almost flawlessly upon install and does what it says. The (2) minor issues we had were due to the theme. The company replied instantly to instant chat and fixed the issues within minutes. Once we get the go-ahead we will definitely go for the paid plan

The app provide precisely what I need. The display style is very clear and unique so that the visitors understand immediately how to get discounts. Furthermore, I had an displaying issue because of my shopify theme and Xavier from the support fixed it very quickly. I tested a lot of discount app and this is the best so far.

I cannot explain how many apps I have looked through to try and get a simple 3 for 2 on a collection of products. I installed this and immediately got offered support on how to do it (I didn't even need the help - its simple steps to do this) Thank you so much for taking it so easy, uninstrusive and fast. I went through other discount based apps and nothing is as easy as this one. Save yourself the time and install this one, don't bother doing what I did.

Excellent app and fantastic support. I had a little problem with using the multi discount where it wouldn't apply the discount to another currency other than the home currency. They are working on a solution (Xavier replied immediately to my email which I didn't expect but greatly appreciated!) but in the meantime, I was able to use a percentage instead of dollar amount and it converts to both CAD and USD. Great app, I will be adding it to another website of mine.

Excellent app does exactly what we need. We can now have an automatic discount running that doesn't stop customers from being able to use other discount codes.

After testing out many similar apps I found that DiscountDuck was by far the best app for our organization. Its extremely easy to navigate and is clean and efficient with the features it offers. The app developer went above and beyond to ensure that the application met all of our needs and had really good communication throughout the entire implementation process. I would recommend this app for any size company , big or small. The price point is unbeatable and the customer service is unmatched. Thank you Xavier for all your help!

I've used this to set up multiple multibuy specials that Shopify wouldn't allow natively. I have hundreds of products which have "4 for X, 10 for Y" discounts, and this app works perfectly for that purpose. It shows the discount in the shopping basket as well which I didn't even think was possible in Shopify. Very good feature!
It's quite customisable in how you set up the specials and how it looks on your website. I had a visual glitch occur and messaged the developers. They very quickly responded and sorted out the issue with polite and clear communication. When using an app like this, what makes it a 5/5 is when the developers are ready to jump in and help like they did. I strongly recommend this app if you need to set up Specials and Multibuys in your store.
