Discounts, BOGO & Gifts ‑ AIOD

We use this app for the Free Gift function, in order to add a discount to all other items in cart when a certain high-price item is bought. This feature wasn't available, so I requested it and Chirag added this feature and replied to me with a custom video to explain how it works - all within 48 hours. I was highly impressed. Although I haven't used the entirety of the app, it's 5-stars from me from what I can see, and 5-stars for the customer service.
