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!

Really useful app for improving the shopping experience! The cart drawer is clean and easy to use, and the free gift feature is a great way to encourage customers to add more products. Easy setup and works smoothly. 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.

Easy to set up and simple to use. The upsell offers work well and are easy to manage.

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 enti...

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.

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

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 custo...

This is a great app and the customer support is brilliant! If I've had any questions or needed any help George and Oscar have responded immediately and been so helpful. SO glad to have found this app for my store!

Best APP for Cart CRO ! Team very reactive & a lot of features is coming !

Verry good service! thanks George!

All the apps from them works perfect for me.I had problem at the begining but the support solved it in no time.Great support and great app.Please make more apps in the future!

We’ve had a great experience with this app. The team is super friendly, always ready to help, and they’ve supported us a lot whenever we had questions or needed guidance. The app itself works really well and delivers on what it promises. Highly recommended!

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.

The support team is fantastic — always responsive, professional, and happy to help with anything we need. The app itself is packed with features, easy to set up, and works smoothly. It’s been a great addition to our Shopify store.

Perfect! The optimizations are thorough, well-executed, and easy to use. The developers respond very quickly and are attentive, all for free!

Great app

Very easy to work with and with great help from the support team the shopping cart was installed correctly (due to bug in my theme, had nothing to do with this app).
