Winterchild Jewellery review for Shopify Planet

I love the concept of this app and am so pleased to be able to offer this product for my business. I found this app was pretty simple to install, however, I am wondering if there is an engaging, detailed write-up along with visuals that I could add to my Shipping section and my Sustainability section. is this something that has been developed and I just don't see it? If it is developed please let me know. I have a question, I recently downloaded the Shopify POS and will be using it at a craft show quite a distance from where I have my business, is there any chance I will be charged fees as mentioned by another reviewer? Could you check into this and let me know? I can remove this from my review after I get the answer, I just don't know how else to find out. Thanks again!
