Sorry to start a post just to ask this, but i asked in another thread and it was never answered. But i could have sworn i read something about this a while back, and i need to know if it's true so that i can buy out the local big lots before it's gone. And if so, how long can i expect a bottle to last on the shelf? Don't wanna buy 5 bottles if the last few go bad before i ever get to them.
