Amai PreOrder Manager + Notify

The app was very easy to install to use. Customization felt a bit limited, but that's also because I didn't really dive deep into integrating it onto my store. Great for beginners who need a pre-order app that just works straight out of the box. I used it for a presale that lasted a week, and the customer service team was readily available for any questions I had. The app also showed the analytics behind which products were purchased, which helped me with putting together my production order since the cheapest Shopify plan doesn't give you this information. I'll be using this app again in the future when I need it again!
