Jacob - awesome!

We've got orders for: 14+10+16+20+10=70 plus $40+50+10+10+50=160/$2.7 = 
59.  That's 129 total, which is close enough to 132 to order the 11 
dozen :-)

Anymore orders on top will be awesome as well, of course.

Kristin - can you confirm how many you want or what you want to spend?
