Sorry I hade not read the fine print.    I sounded good.  My scuba
dive club decided to put club logo teeshirts, mugs and the like on
Cafe Press and sell at $1 over cost with the profit donated at year
end.  That meant no one had to do anything, no taking orders or
collecting money.   Then I found that Sparkfun was setting up about
the same thing but for PCBs

futerlec can build 20 of the above PCBs for US$99, that's $5 each.
plus shipping.  And all 20 have to ship to the same address.
Futurlec is an Australian company but mostly run in Thailand they have
offices in US, AU, UK and asia.   They can also stuff the boards and
supply parts.     They are my #1 parts source but have limited range
so I have to go to the other places for the more rare items.   Just
for curiosity I got a price for 10,000 boards.  It drops to $1.56
each.   $2.16 for 100.   But I'd bet 20 is the upper limit.

I have no idea how that compares to your cost.
