Saint Jack Cosmetics review for Monster Cart Upsell+Free Gifts

This app is a great addition to my small Shopify store - I don't have many SKUs so this really increases my AOV. I had a handful of issues when installing, reached out to customer support & received literally IMMEDIATE assistance and the issues were fixed in no time at all. Keen to keep tracking the ROI for this app, seems to be very reasonably priced for the hard work it does.
