CRO Cart Drawer & Free Gifts

Really impressed with Thunder Upsells. The app is easy to set up and the cart drawer looks clean and professional. I especially liked the upsell recommendations, free gift options, and progress bar features. Everything works smoothly and fits well with the Shopify store experience. Great app for improving the cart experience and increasing average order value. Highly recommended!

Easy to set up and works well with our theme. The cart drawer upsells, progress bar, and bulk discounts were simple to configure, with no coding needed. The support team was quick to respond when I had a question. I'd recommend it to any store owner looking to increase their average order value.

Absolutely incredible app and an even better team! The app is fun, easy to use, and has made it so much easier to create upsells and improve the overall shopping experience.

The team is incredibly responsive, helpful, and genuinely cares about getting things right. Whenever I’ve needed help, they’ve been quick to jump in and make sure everything is working perfectly.

A huge thank you to the entire team for the amazing work and support. It’s rare to find an app where both the product AND the people behind it are this good.

Shoutout to George. He is incredible! Fast, generous, super helpful, and always willing to go the extra mile.

Highly recommend Thunder Upsells to any Shopify store owner looking to improve their cart experience and increase conversions.

The best cart drawer app we've tried.
Looks well designed, almost all functions we needed.
It helped us to boost average order value at least 20%.
Also, the customer support is always here to help.

Very useful app with a simple setup and great features. Easy to use and a great choice for Shopify store owners. Recommended!

Thunder Upsells offers some useful features for creating a better shopping experience on Shopify. I like the clean cart drawer design and the flexibility to add product recommendations, free gifts, and progress bars. These tools can help encourage customers to explore additional products while keeping the checkout journey smooth and convenient. A useful solution for Shopify merchants looking to optimize their cart experience and boost average order value.

Has everything I need (pricing progress tiers, buy x product, unlock y product for free, bulk discounts, recommended products, one-click upsells). I was very pleasantly surprised by both the feature-set and the backend functionaility (some of these apps cannot add a product automatically to cart, but this one can luckily).

Recommend, and they had helpful support when I needed it.

Really happy with CRO Cart! It had the easiest setup from all the apps I tried for my free gift offer but I actually started doing more upsells from the bulk discounts. Plus the support team is awesome - they're quick to help and everything just works perfectly!

Best free cart app I've found and the dev team is active- very willing to help and debug

FYI This app does NOT support currency conversion. If your storefront handles multiple currencies (Markets -> Region -> Currency Select -> Use Local Currencies), several features will not fully work for you. E.g. The total cart value displays in your default currency, while the items in the cart use the customer's local currency. This leads to summed item cost not 'equaling' the value displayed for the cart total because the currencies don't match which you wouldn't notice until after you've already set everything up and are testing it out for different regions.

Perfect App, perfect Support! We've done around €34000 in upsells through the app! No better App out there
