Lowest cost laser modules?

Where can I find the lowest priced red laser modules or pointers? I know dollar stores sell laser pointers for around $3 each. I do not need the entire pointer, just the laser module itself, but I dont mind getting pointers as well, since I can take the pointer apart anyways. If anybody has any links about where to order them, can you post the links here?

Thanks
