Jo-ann - I got mine from Lowe's early this season. The one with the grids I use for peonies or the taller asters. The one without the grids (just the ring), I use for Achilleas or any plants that got a tendency to flop. For some reason both supports, with or without grids were only $2+change - less than $3. It was only a few cents difference between the 2.
Home Depot were charging more for the one with the grids. So I thought maybe Lowe's made a mistake in their pricing. But hey, whose complaining?!
