Just thought I would mention that I found grids in Walmart, since some people seem to be having trouble finding them. I got 12 of them for 17.99. I believe they are available at Home Depot, but I didn't see any there. In Walmart, they were in the section that has laundry baskets, large tupperware storage containers. They had white and tan colored ones.
