uncertified

This board comes from an uncertified manufacturer
We won't be able to provide any support if it doesn't work as expected."
and i buy a kit from amazon and this is the link for the kit http://www.amazon.com/Arduino-Starter-Official-170-page-Projects/dp/B009UKZV0A/ref=sr_1_3?s=electronics&ie=UTF8&qid=1428687224&sr=1-3&keywords=Arduino

And . . ?

i was asking how to check if it is uncertified and i know how i found that
because i found on the box www.arduino.org not www.arduino.cc
so my second question do they different from each other

What did they say at arduino.org?

they just sale Arduino boards
so i would like to ask you if there Arduino is good
and the problem that i bought mine from amazon and on the box on the photo it was www.arduino.cc
i don't know how this happen and can i make amazon replace my Arduino
