Quickly responded to my request and changed an issue within a day! Super appreciative and very happy with the customer service/product.

Edit - months later they still support us and the app. They are very helpful and responsive in development support, and were quick to address and solve any bugs that our template caused. Great team!

A simple and clean app for that works as it should – perfect for small cart add ons. It didn't install and seamlessly as I would have hoped, but I'm guessing that was more of a theme issue then their app. Angie was great at getting me setup and the module placed exactly where I wanted.

We do not charge for shipping, but we do charge a flat packaging and handling fee. This app works GREAT for us. The staff has been helpful and quick to respond when needed. We have been using this app for a couple of years now with nothing but good results. I would not hesitate to recommend giving them a try, They've been great for us.

Does exactly what it is supposed to do. I had one small problem with the surcharge not being required for certain people, but their team fixed it promptly. Thank you!

The plugin works as it should, we use it to add a tax free deposit fee to our products. The support experience is very positive and prefessional.
