I thought that I would workout how much a dongle parts coop might actually save.
It looks like above 25 units, with a case, the savings would approach $10, and level out at around $12 from 50-75 kits.
I also included some shipping reference costs that might be useful for others interested in running a coop.
If people find it useful, I'd be willing to do the same for RJ's other projects.
