Buying Arduino Student Kits/Education Starter Kit

For buying the Arduino Student Kits/Education Starter Kit, Can we only buy from the Arduino website or from anywhere else?

I need the other website, to have exactly the same equipment including the online content where they teach Arduino.

just look on ebay, bangood, amazon...

Also try yourduino.com

In those services, the kit is there, but one problem. I think it won't be provided with the online content, only with the hundred pages... I am looking for the online content and the same equipment needs to be there
