Kaching Bundles App & Upsells

Very useful app, I'm using it to offer quantity break discounts on my products. Easy to use and customise the appearance, intuitive for customers. Unfortunately (through shopify rather than any fault of the app) you cannot combine discounts with your bundle discounts - I was trying to offer an additional 10% with email sign up but sadly cannot be done. Helpful and responsive support team who were able to edit some error messages for me.
