Yes, you are right. Though, crypto payment option isn't the only thing that is different from Amazon.
Right now, by the end of sept 30th you will see the buying.com iOS and Android app MVP. The deadline for the app is for Q4 2018.
In the next days, the first portion of the yellowpaper will be released as well presenting the protocol and its "capabilities".
