sales tax

[Carl Root]

If you replace a hammer shank, you have sold them a part so you have to
pay tax. Yes? No?  (assuming you pay taxes for sales , but not
services.)

How about a set of keytops?  Hammers?  Dampp Chaser?

What we're really interested in is the ratio of service cost to
'materials'cost and is the 'materials cost' sold as a stand alone item
without installation and in sufficiently large numbers to make it
worthwhile for both the State and you to pay attention.  

Doubt it.  Unless you're selling pianos.
