As a B2B company, we wanted shopping carts to be saved for 90 days instead of 30 days. We submitted a request to Casper, and after 5 days we received confirmation that this had been implemented. Our customers, who sometimes take several days to complete an order, are very satisfied that they can now continue working on their order across different devices.

Developer repliedThanks so much for the review 😊 Requests like yours are exactly how Casper keeps evolving, so thank you again for taking the time to share your feedback. It’s always a pleasure to improve the experience for your customers with Casper! Clément. Show more

Developer repliedThanks a lot for your review! I’m really glad Casper helps your customers keep their carts synced across devices. Thanks for your trust! 😊 Show more

This app is a game-changer - well-priced, incredibly effective, and solves a major shortcoming in Shopify’s native functionality. Since implementing it, we've seen a significant boost in customer satisfaction. Clément is highly responsive and has even implemented new features based on our feedback. Couldn't recommend it more - truly a 10/10 experience!

Developer repliedThanks so much for the amazing feedback! Really glad Casper has been useful! And it’s been a pleasure collaborating on those improvements. Clément Show more

Such a simple solution to such a silly Shopify limitation. Incredibly easy to install and get going. Carts are now syncing across multiple devices, including items with line item properties.
