Really happy with Addonn so far. It allowed us to add options like a gift wrap and a cross body strap directly at checkout, which our customers appreciate because they can easily choose the extras they want. The app is easy to configure and works smoothly with our store. It’s a great way to increase order value without adding friction to the buying process.

Addonn was exactly what we needed to offer optional services. Setup was quick and the add-ons integrated nicely without disrupting the checkout experience for our customers. We’ve already seen customers selecting the extras, which is a nice boost in additional revenue from orders we were already getting. Simple app, clean interface, and great support from the developer whenever we had questions.

Addonn makes it super easy to offer optional add-ons directly in checkout. Setup was quick, it feels completely native, and support has been excellent. Highly recommended for anyone looking to increase AOV without hurting conversions.

Addonn is exactly what i was looking for, Best and one of a kind app i found so far for upselling add-ons at checkout on Shopify app store. Customer support is very responsive and helped me set up the app correctly on my store, I wanted little custom functionality and it got delivered in just couple days. The best part is that it works without adding any additional codes to the theme. I highly recommend it!
