I'm not interested in doing a retail hit-job here, but just a word of informed warning.
I recently worked for a lab in New York, and from time to time we had to scramble for different sized RC papers, Fuji and Kodak. This would take me to various dealers to get off-the-refrigerator-shelf paper.
Adorama is a great place for most things, but they practice some very murky dealings with there no-return color paper. If its not past-expiry, its been physically abused, and is often inexplicably dirty. I mean real dirt dirty, not just dusty. The external dirt is ok for a sealed paper box, but the man-handled boxes would sometimes have whole-box kinks in the paper stacks because of past abuses.
As for roll paper- edges of the rolls themselves were often dented. Unfortunately, this also often applies to their inkjet rolls, particularly Ilford, but that is for another Forum. A recently purchased and half-destroyed roll of inkjet paper inspired me to pass on my past experiences.
They may not even carry RC paper anymore- the last time I went for paper was months ago, and they seemed to be running down their stock to its dregs. As for their direct order paper from the internet, I cant say. Perhaps it only gets man-handled in the 18th street store. Hopefully, the situation has even improved recently- just be sure to check!
If its gotta be Adorama, go in person and ask to see the boxes before you get to the counter!
