Using the customers shipping information, cart data and your Amazon seller account, we send really REALLY fast carrier pigeons(or the Amazon API) out to Amazon. Once there, they pick up all the fees Amazon is deciding to charge then turn around and provide these to you. We then look at the settings within your account to provide the final fees to your customers.
Our app is embedded in the admin section of your store, works through Shopify, and if you type fast, can be setup in less than one minute.To get setup we just need a few identifying pieces of information from your Amazon account, plus your shipping rules and you're done.
