Fry's has a NiteIze key chain with six #1 S-biners for $2.50 in their current Friday Ad, good until next Thursday 09/08/11.
I like to use these little guys, they come in handy for all sorts of things...
those little guys usually sell for $2.50 elsewhere for a set of two, like at REI
PS: these are the little plastic ones, they are not made out of metal.
