I called about 6 different places here in Minneapolis, and no one will sell it to me because I'm not a contractor. I'd rather buy it locally so I didn't have to deal with shipping (especially since it's getting cold and it probably shouldn't freeze).

Does anyone have any suggestions? Private message me if you have specific suggestions on where to buy to keep that stuff off the board.

You will have to buy mail order. Ken doesn't sell it here so I don't think he will mind recommending buying from other online sellers. It is freeze thaw stable.
