Threads By Cali review for CartKing ‑ Auto Add Free Gifts

July 10, 2023

I went thru so many upsell / free gift apps on shopify, and finally settled on this one. It has exactly what I needed, is super easy to use, and the customer support has been amazing. Would strongly recommend this to all shops who are looking to offer free gifts for specific items. We'll be sticking with cart king for a while! - cali
