Flex Upsell Cart has been a great investment , not only has made managing offers easier and has increased my AOV but you also have excellent customer service and personal attention . with this app you get more than code you get a technical partner !

Managing the technical side of my shop was overwhelming and I felt totally lost but Flex Upsell has made it much easier. They completely revamped my cart to make it more user-friendly and helped me set up upselling options that actually made sense for my products. They took the time to understand my needs and delivered a solution that has genuinely helped grow my business. Five stars!

We’ve been using Flex Upsell Cart on both of our sites and we LOVE it. Seriously one of the easiest apps we’ve installed—setup took just a few minutes and it worked right away. The upsells and cross-sells blend perfectly into the cart without feeling pushy, and we’ve definitely seen an increase in order value since adding it. The free shipping progress bar and cart offers are —customers actually respond to them. What we really like is how flexible everything is. It’s super easy to test different offers, discounts, and gifts without needing any dev work. Overall, this app just works and makes more money without adding friction. Highly recommend!!

My experience with this app and their customer support team so far has been top notch I want to give a main thank you to Nick as he helped me a lot with my website and fixed a few issues I had.

Great app for upselling. Excellent and fast customer service. Easy to navigate. Highly recommend

Great customer service and increase AOV made by introducing this app to our checkout. Its been a pleasure working with the team,

Really impressed with this app. Already seeing an increase in AOV. Support is also fantastic, Nick is so helpful and accommodating. I highly recommend installing this app on your store.

The upsell offers feel smooth and well-placed, not pushy, and the auto-discounts and free-shipping progress bar are great for increasing average order value. Setup is straightforward, the design blends nicely with the cart, and everything runs without slowing the store down. Overall, it’s a great choice if you want an effective, user-friendly upsell solution that actually converts. Highly recommended!!!
