I won't rehash a review of Joe Rodgers' Office Supply in Cleveland, Tennessee (outside of Chattanooga), but if you're ever in the area, it's every bit as good as Bob from My Pen Needs Ink makes it out to be. (Link Here to his Review). They have a large fountain pen section at the front of the store that features Conklin, Delta, Visconti, Waterman, Parker, Sheaffer, Lamy, and well, lots of other brands. They also have a floor to ceiling ink cabinet that is packed full of ink, including THIS:
Don't go inundating them with phone calls, now, because I got the last bottle. However, they did have some late-1990's vintage bottles of Montblanc Black, Emerald Green, and Ruby Red. I picked up a bottle of Ruby Red as well but have not tried it out yet. The best part? This:
Apologies for the blurry pic, but yes, they honored that price. $8.25 for a bottle of discontinued Montblanc Bordeaux, which I might add, is probably the best burgundy ink I have ever used. I compared it to the new Burgundy color at the DC Pen Show Ink testing station and the new ink is much lighter.
Unfortunately, I stopped by Joe Rodgers on a brief detour from a work trip, so I did not have time to seriously root around. Who knows what else you might find?
