Flex Upsell Cart Auto Discount

This checkout cart app was super easy to set up and immediately improved my store’s conversions. The features are simple to use and really help drive more sales. Plus, the customer support is outstanding—quick, friendly, and always helpful. Highly recommend!

We’ve been using Flex Upsell Cart for a while now and it has made a noticeable difference in our store’s performance. We’ve processed 1,100+ orders using this cart, and the upsell and discount features integrate seamlessly into the checkout experience without disrupting conversions.
The automation options (auto discounts, free shipping thresholds, and upsell prompts) are easy to customize and work exactly as intended. It’s been especially helpful in increasing AOV while keeping the cart experience clean and user-friendly.
On top of that, the support team is extremely responsive and helpful. Any time we’ve had a question or needed clarification, they’ve been quick to assist and genuinely care about helping merchants succeed.
Highly recommend this app to any store looking to optimize their cart and boost conversions with reliable support behind it.

I used this app on my store and I’m very pleased. The setup was straightforward and worked seamlessly with my theme. It helped me increase average order value by enabling clean, easy add-ons (like gift-wrap, insured shipping, etc.) via simple checkboxes. Customer adoption was higher than I expected, and the upsell process felt smooth and non-intrusive. Support was responsive and helpful when I requested a custom tweak. Would definitely recommend to other Shopify merchants.
