Does anyone know where I could purchase Decon Cannisters and small, "strong" magnets locally around the Phoenix area?  I have the addresses where I could send away for the items, but I would rather find a local supplier

I've tried Larada's Army Surplus in Mesa for the cannisters, but they don't have them.

Thanks,
