No, it's been mentioned before.
I think it was $11.50
The prices vary somewhat due to quanity ordered, so none of them are written
in stone.

Let's not be bashful, let all

No.
The is about volunteering, and folks do have a life, and don't have deep
wallets to inventory things.  So you need to get involved, and watch the
postings.  This is an ongoing project.   Also, the case I used was a Radio
Shack item, mentioned in the archives.  This is all now just jelling, no
one's had an affordable WB before, so it's not like your missing anything.
Just take a deep breath and relax a little (in reference to the NOW).

This is also been gone over.
Boards on the first buy were 3.15.  Again since at cost prices vary.

Now stop it.
He's been doing alot of work, and invested a small fortune to do this.
Don't pick him apart for his efforts.  If he wants to write or not, so be
it.  Sorting out 50 pieces, and packing up hundreds of these kits is a huge
investment in time.  He needs to recovery his investment, so to him right
now, packaging, and mailing kits is more important then the weekly thread of
what's new.
