Yes - The Mountain Goat in Hanover was the only place I went that had an abundance of esbit. And would you know that I sent a package containing just esbit there!
Gorham Hardware and Sports had a few boxes but the place across the street - Moriah Sports - who were just changing their name to something else (Altitude Sports maybe?) did not have any. However, thankfully I was able to pick up some Leki's there because the Whites ate my Black Diamonds.
The Mountain Goat in Hanover, NH should have it.
You could ask.

There's also a small outfitter in Gorham - if he's still in business. The store didn't look to be doing very well last time I was in there.
