Amp Slide Cart Upsell Drawer

We haven't lauched this app yet, but I am so impressed by their support. They respond quick and solve my problems well. One time our storefront had a bug and I asked them if it is caused by their developers' changes on our store. They kept that in mind, and always use a copy for any changes they done with a note telling us what's the change. I tried a lot of apps and trust me they are excellent and reliable. The app is also great! The setting is highly flexiable. Love it!
