The support team is great! needed to do a quick custom modification and they went above and beyond! the app itself is great too! works like a charm!

The app works exactly as advertised, and it's easy to use.

It automatically creates and applies a discount code for any specific quantity of any product you choose (for example, buy 2 get 15% discount, buy 3 get 20% discount, and so on) and places the code to the right place on your product page. So no need to manually add any code snippets, which is great.

The design (colors and fonts) is automatically inherited from your theme, so it doesn't look out of place, which is also great.

So yeah, I'd recommend this particular Quantity Breaks app.
