Crosslinks via eBay offers the 6x50-Foot Privacy Screen Mesh Fence Cover for $39.95 with free shipping. That's $2 below our mention from last month and the lowest total price we've seen for such a fence. (It's a current low by $2.) It features 85% visibility blockage and 52 brass grommets.
Of note, this is a fence cover, not an actual fence.
