Kinetics Cosmetics review for Bigblue Automatic Free Gifts

This is the worst app I've ever tried. I tried to create a campaign for a free product and when I went to add a discount code it said the code doesn't exist and it wanted me to create one in Shopify discounts first. Why would I even need this app if I could create the discount in Shopify??? When I tried to get some customer support they make you go through one of those automated live chats that never connects you to a real person and doesn't help answer any questions. Don't waste your time, this app is terrible.
