We really love the Smith & Hawken store over in Marin. We recently stopped in because we heard they had a sale on their copper planters, and being that we're copper fanatics we wanted to see it for ourselves and grab some. We got some great copper products, and for a fantastic price.
The ones we purchased (copper trays) were $12. But! They have a huge selection of all things copper, so you should either make a trip over there or check out their website.
