The only app I could find that would meet 90% off my needs and support is just amazing so quick to reply to email and would definitely recommend this app to anyone. If you can make this app work with ajax cart that would AWESOME!

Thank you for the amazing review.

We plan on developing our own ajax cart that is compatible with our price add-ons but we have been very busy lately. We'll email you when it's available.
