[Neuro] Neuro Digest, Vol 32, Issue 4

My markup is only 20 dollars per device.  For every 25 I source, build,
test, and sell I get 500 dollars.  I'm not exactly becoming
a millionaire here.   My costs to build them is 50. If I were being a
proper capitalist I would be charging at least 100 because that is double
my cost. Many people say you can only keep a business afloat if you charge
3 times your cost.  If you can find an adjustable current,current ramping ,
assembled and shipped tdcs device for less than 70 please link to it.  I
don't think you can though.  Can you build one yourself for cheaper?  Of
course*
*(ignoring your own labor costs)
