You could take a look at a couple of SF places like:

http://www.photosupply.com

but if I were you, I'd find someone with a computer

As of today, 48 pages of Nikon mounts are available,
for a grand total of 2,274 items, and that's pretty much

you're looking for are much higher than in any store,
no matter how big it is.
