Matrixify

I am awful with spreadsheets and have had a very manual process uploading products from Shopify to Amazon. This app changed all of that. I had a little tough time figuring out a small uploading portion so I contacted support... They not only fixed the issue, which was totally my fault, but they also went WAY PAST the expected help to make sure every product was uploaded. This is resulting in literally doubling the sales for my Shopify store.
