This is actually an ongoing, ever-changing gloat. And it is also a "heads up" to you all if it happens to be available in your local HD's.
I am making it a regular habit to stop in at my "local" HD and do a walk thru for deals (you know, closeouts etc.). BUT, I am also making it a habit to checkout their selection of cull lumber. It seems they regularly cut up stock that has been damaged, or whatever, into snaller pieces and sell them GREATLY reduced. Regularly, I can pickup 4-5' 2x4's for $.51 each. Sometimes I am even treated to 2x10's and 2x12's for the same price.
Today, however, I came upon 1/2" MDF. 2'x4' sheets for $1.01. I bought 6. I also got some 1x6 poplar for $.51.
I'm happier than a pig in slop.
