Pumper Bundles Quantity Breaks

I’m extremely disappointed with this app. Despite reaching out for support, the issues I mentioned were not resolved. The support team’s knowledge is very limited, and they couldn't fix the problem I was facing. In fact, my store content was altered without my consent. The promises made by the app and the support team were not fulfilled. I wouldn’t recommend it to anyone, as they were unable to add the features I requested and left my store in a worse state than before.

app is literally broken for Black Friday..

I've had this app break multiple times just out of nowhere and I've lost literally thousands, any other app won't break like this and cost you, so be very careful, also it's very basic compared to others.

The app simply doesn't work. I've spent weeks in the chat trying to solve my problem but they have no idea. I've created quantity discounts on my website. A customer will purchase multiple items that should qualify for quantity discounts and they get maybe 1 or 2. I've rebuilt everything and promised that "it's fixed" multiple times with no resolve to the issue. I really wanted this to work but the app developer has no idea how to write the correct code to get it to work. I would stay far away from this app unless you want angry customers for not getting the discount they are promised.

The app has a bug on volume discount, I setted buy 3 can get discount, but when i buy 4, all of them can not get any discount. And they can not fix
