Stamped Reviews & Loyalty

I am just starting to integrate the app into my Shopify store and cannot give a a complete evaluation yet It might be higher after I really have a chance to use it. I like the features and have it partially running on my site. I wanted to test drive the free version before deciding, which paid version would work best. There is no support for the free version so I am trying to find Youtube videos to help with my specific issues but this has been very time consuming. I am not a techie and run the store by myself, so I do not have a lot of time to invest. It would be nice if there was a good learning resource to help with the process of getting it up and running properly. Hopefully I can figure things out and get the most out of it.
