Not to be argumentative but, large accounts? Who exactly? I saw some "talk" (aka a P.R.) but no solid information just speculation on who or what or how many. Can't see it being a contract issue because as you say they've bought product so wouldn't the contract have to be in place?
I'm not saying that MINE won't (maybe) someday be a winner but it doesn't look like it will be in my lifetime. Hang your hat's on MMJ rumors and "big deal rumors" all you want. I'm sorry but I'm out.
Would the last person out please shut off the lights??? LOL
