More good news, we have a confirmed $3.016/laser price if we order 100+. 
  Currently the order total is ~110.  I'll wait till late tomorrow to 
put the order in, so the people on noisebridge-discuss have time to put 
their names down too.

Jacob - I will ship to you, do you want them?  We do not "need" you for 
scale, but there is another discount at 11 dozen (132) that it would be 
cool to hit.  At 11 dozen, $355.37/132 = $2.69 each.

Tim,

Thanks for your quick response. How do I get the discount? The item page 
only lets me order 10. If I put 100 in the box it changes it back to 10.
