Shopify Marketplace Connect

I've been having issues with integrating my Shopify store across to Amazon. This app worked well to get my store across to Ebay and Google, but Amazon is a more complicated beast. Jae at Codisto has been great fixing some issues I had with SKU's and UPC's so I'll be jumping back into Shopify Marketplace to have another attempt at listing on Amazon. Thanks Jae for the help and advice.
