Kite Discount, Free Gift, BOGO

Really easy setup.
I just ploughed into it blindly and it did exactly what we needed it to.
Shopify wouldn't let us do a Buy X, get Y promo on a product which already had an amount off product discount. With Kite this was easy and possible.
Support were right there helping us to tweak and get it perfect.
Great App - Highly recommend.
