Booster: Discounted Pricing

We've had this app for many years, and it was working well. With recent changes however, it no longer works properly and support is poor. First it frequently crashed customers' carts. Those that didn't crash just had the discount disappear at checkout, which made it look like we were deliberately offering a non-existent discount. We had many customer complaints. Shopify told us to keep it installed so it could be fixed, which was brutal. Eventually I decided to uninstall and look elsewhere. After several weeks it was 'fixed' and we had it reinstalled. It now takes the discount offered on one item and spreads that out over all the products in the cart. A $10 discount on one item now becomes $1.67 on that item and so on down the cart. It looks ridiculous and is confusing. I should say that strongly suspect that the issues this app is having are because of Shopify code changes that they have not acknowledged and have caused problems to many apps and themes. Still, Shopify apps need to be able to adapt in the Shopify environment.

Support for this app is a total disaster. Never in my life have I encountered such an unprofessional and ignorant approach to the customer. Support does not listen to customers, they pretend that the problem has been solved and do not write back. I pay for a subscription, and when I had a problem that prevented me from opening the store, support ignored it, did not write back. I had to change to another app. I do not recommend the app, bad treatment of customers, waste of time and money.

Customers can't go to checkout due to some app issue. Have to uninstall and look for another solution. Support didn't resolve the issue for over 3 weeks...
