What merchants think

Feedback submitted

Merchants say this app boosts sales and customer experience with auto‑added free gifts, clear cart discounts, and higher average order value. They like its flexible “buy X get Y” rules, tiered gifts, non‑purchasable gift support, and control over dates and stacking. Setup is described as quick and intuitive, the cart design clean and reliable, and support exceptionally fast, hands‑on, and open to adding requested features.

Tried more than 100 apps and Cart King is 100% the best I've tried.

If you want to use their Gift Feature it is perfect, they also have many other features that have helped my business grow.

Customer service is outstanding. They have helped me trouble shoot my website for errors, put the offer up in the basket as I wanted and helped me with it all in the chat for over 2 hours, completely free.

Huge recommendation from here. Best app ever.

Greetings very happy customer, Martin Egsvang Jessen

I recently used the "CartKing - Auto Add Free Gifts" app on my Shopify store and was incredibly impressed. The app is outstanding for boosting sales and customer engagement. Vivek, from the CartKing staff, provided exceptional support throughout. He promptly addressed all my queries and went above and beyond to resolve any issues I encountered. The app seamlessly adds free gifts to the cart, enhancing the shopping experience and driving customer loyalty. Its user-friendly interface and customization options make it a breeze to set up. I highly recommend the "CartKing - Auto Add Free Gifts" app to all Shopify merchants. Thank you, Vivek, for an amazing experience!
