TrueGrid Grass or Gravel Driveway Pavers

$1600 on Amazon today, so this is half-price. We installed these to stabilize gravel and grass we installed in our driveway to replace asphalt and allow rain to drain through instead of flood our property. It installs pretty fast whether DIY or by your contractor. We love it, but bought a bit too much and this is the surplus we've been storing in our garage loft. We have 9 boxes with 10 24"x24" pieces in each, 360 sqft altogether. The manufacturer's website is at truegridpaver.com.
