I am not too sure about celluloco, take a look at their reseller ratings

http://www.resellerratings.com/store/Celluloco

There is even mention on the review of someone buying some samsung phone because it was purple but the phone they recieved was black and being told that they do not guarantee color of purchase...

Also they seem to be selling a N950 also...very odd since they're not too many of those floating around out there, I'd avoid them based on their ratings and carrying colors of 64gb that aren't really anywhere else.
