I was lurking on the Chicago board when I saw the word "Pastrami". It seems a place called Zingerman's has mail order Deli.
Interesting Jewish breads and Jewish baked goods. Link is below. They are a gourmet goods site as well. Some of the prices are kind of outrageous. Reuben Sandwiches for two $75. They do include pickles and potato salad though. If you have money to burn... The Chicago posters were complaining about the $14 per pound for pastrami by mail. However, I'm paying $11 per pound for ham at Andronico's.
The only other mail order deli I found was the Second Avenue Deli in New York.
The internet is so wonderful. Mail order pierogis and even fried clams...
