In Springfield MA Walmart turned one store into a superstore. (HUGE) Coca cola filled the new stock space with soda. The Manger there told them he would start charging them for space if they didn't get their overstock out. "They did" RMHB will get space when customers ask for it, and when we give the store manager the pitch.
It's already cheaper than Monster, and better for you.
So it's a matter of time.
Nothing more.
Easy to sell it on it's own merits.
