Amazon MCF by ByteStand

This app solved my problem when Amazon's own app could not. We only have a single SKU at Amazon but wanted to sell multi-packs on our Shopify store. So this app is enables us to sell 2-packs and 3-packs of our single SKU item in Amazon. In other words, this app enables us to ship "Virtual Bundles" to our Shopify customers and fulfill from our single units at MCF (FBA).
