Knob Zone review for Quantity Discounts ‑ Bundles

A very good little app for providing volume discounts for multiple item purchases. We have tried many different apps and this was by far the best! The support is very responsive and helpful. When they weren't available on the live chat they got back to me by email promptly. One important feature for us was that it calculates discount amount exactly, without rounding the line item unit price (e.g. 10x £0.05 items @ 10% off = £0.45 total). Other apps we have tried take 10% off the line item price then round it to 2 decimals before summing the total, which would result in no discount being applied.
