Where is the cheapest place in North Carolina to get a Tenor Recorder in C?

somewhere less than 3 hours from Wilson, NC

If you're in Wilson, contact the Music Department over there at Barton College and ask them where they buy their instruments.

Most music stores either have recorders or can order them. I am not familiar with your area of the country so I do not know which music store chains you could visit. Contact the closest chapter of the musician's union because they will know who usually has the best prices on new and/or used instruments.
