$40 · Interlocking foam mats

Mainstay interlocking foam mat. 24 - 21.4"x21.4" mats. I had it laid out in a 5'2"x13'8" workout area. Water resistant, durable. Good shape other than indentations from the workout equipment. You can buy more of them at Walmart if this isn't enough at $15.64 for 4 with tax. So I paid $93.84 for them. Selling them all for $40.
