Would like to see if anyone else is interested in a group buy for an Autism Awareness PBT dyesub cap. My 4 year old son is Autistic and I would like to spread awareness, and what better way to do it than through my new hobby? 
Meiosis had an idea to open this up to other disorders / disabilities, and I think that's a great idea. If you have other initiatives you would like to see caps for to raise awareness this will be somewhat of a charity benefit. 
With Meiosis' support we have met the MOQ for 50 caps. Let's keep it going and everyone submit their ideas so we can make this a great charity related Group Buy!!
The Autism cap would have the image:

qtan's pricing tiers are as follows:
| MOQ | Price/ea | 
| 50 | $3.50 | 
| 100-199 | $3.30 | 
| 200-500 | $3.00 | 
| 500+ | $2.50 | 
The_Beast recommended upping the price of the cap to a flat $5 and donating the remainder to an Autism research / support related charity. I like this idea and would like others opinion on it as well.
Potential research organizations:
Autism Research InstituteOrganization for Autism ResearchInitial color suggestions for the base cap would be black, white, red, blue, or yellow. Can make a mixed order if there is enough interest, but that will effect the price per 
qtan's post in his vendor forum.
