Why is aluminum diamond plate so expensive, I went to lowes today to try to get a piece or 2, and a 1ft by 2ft piece was $37, and a 2ft by 4ft piece was a hundred frekin dollars, but the day before I went to the scrap yard and got bout 1.5 square foot 2 different pieces for $2, they were like brand new just a little piece taken out, what the hell is goin on.
