So there is a BB&B store closing by me and I happened to ask about the wall fixtures. I ended up buying 112 sq ft of this paneling that I will use for my garage walls and one 16 sq ft section for my workbench in the basement, all for $70. I also bough boxes of 50 of each type of connector they had for $5 a box. Mega score.
