I've been a bit leery of saving oyster shells and reusing them. I guess if I soaked them in PBW or something similar, they would be safe to use again?
@5698k - I've ordered oysters and shells before (shucked oysters and the shells on the side), but the shipping costs were pretty high, as I recall. This just seemed a nice, clean solution to me. But, at the rate that they are going, it's not likely that it will get fully funded. Pity, as it's a great idea for us "land locked" seafood lovers.
