are you in the SF bay area?
if you are, you can either contact speedie408(nick), or buy them from a guy that is selling on cragslist, he is in San Jose as where Nick live.
Last time I bought 20+ shrimps for $1 per, from cragslist, the shrimp looked weak, small and pale but after they shred once in my tank, turned out all completely red.
The craigslist guy told me the shrimp were fire red but not in good environment(outside bare tank), so not looking good. what he said was true since the shrimp went from ugly ducklings to swans in two weeks in the planted tank.
