YMMV – Select Lowe’s Stores: Blue Hawk 12-ft x 20-ft Polyethylene Tarp Clearance – Prices Vary $11.30

Looks like most stores have this for less than $12. I ordered a couple for pickup at $12.30 Good luck if you are interested. Check the boxes above the tarp section if you don’t see it on the floor.
