Kris:
Have you tried ebay? There are some good vendors there and once you buy from one you can go direct.
Back when I was doing middle school dances I used laser pointers as a give away (don't do that). I found a few good sources for those and bought direct after the first purchase off of ebay.
Sometimes you can get them cheaper directly.
You can get them from my Makes party ling on my website
Kris if you need them in a hurry, US TOY @ 103rd and State line carries them.
