Sharp Prices via eBay offers the Grassology Grass Seed 3-lb. Bag 6-Pack for $22.99 with free shipping. (Midwest Service Closeouts via eBay has it for the same.) That's the lowest total price we could find by $7, although we saw it for a buck less a month ago. It purports to grow roots that are four times deeper than ordinary grass. Each bag covers 750 square feet.
