Six for sixty bucks. FLOR has now introduced 6-tile boxes of their modular flooring exclusively at Target. Use just one box (about 18 square feet), or buy several and mix and match...There are only four styles available as of now: Bright Stripes, Basic Stripes, Bright Solids, and Basic Solids. Note that these are currently available online but not in stores.
(thanks for the tip, Gabrielle!)
