Cerith Snails in Calgary?

[Enigma]

Red Coral doesn't have any.
Gold doesn't have any (they're on order)
Pisces doesn't have any (they're on order)
Ocean Creation . . . he didn't quite seem to understand what I was looking for (tried to sell me Nass snails)

I haven't checked Big Al's or Riverfront (I prefer not to shop in either place).

Does anyone know of anyone who does have them in stock? I only need 2-4 of them.
