I'd like to try it for backpacking, but not interested in a subscription. Give an option to purchase a sample pack.
As a side question: what's the shelf life of Sudden?
The shelf life is around 4-6 months - we recently started to flush the tubes with nitrogen so as long as you keep the in cool, dry and dark place they'll last for a while.
Has anyone 'hacked' your coffee - I'm thinking of the Aeropress community and the nifty things they've done.
Have you demoed this anywhere in person?
For instance, in Austin people stand in line early in the morning for BBQ, and I'm sure you would make a huge impression if you gave out free samples a few times.
