FWIW, I can confirm that NGCG had a booth at the Wencar tradeshow in Corpus Christi, TX from 11am - 6pm on Friday 1/29/16. At the American Bank Center (fairly large food / tradeshow)

There has been "chatter" that the cups will be in some ampm convenience stores as well but I have not been able to confirm how many as yet. ampm stores are part of the BP (gasoline) footprint. Approx 950 store locations / minimarts mostly out West
