I would also try marketing to Firehouse Subs. http://www.firehousesubs.com/

If you have never been, they make delicious subs and have a large selection of hot sauces. Probably over 50 different types in each store.

Also, you can "droplift" -- print up a label with a bar code of another hot sauce at the price point you want -- and leave them surreptiously on store shelves. Have directions on the label to a website where you can order more.
