Don't know if they are still active, but there was a company based in Orford, NH called the Euphonon Co. I bought strings from them for at least 10 years when I was actively performing. They were the manufacturer for Guild, Ernie Ball, Martin, etc. They would to send then to me in bulk. UPS-Ground. I'd buy a dozen sets @ about 1.50 per. I'd get 2 dozen D(0.35)and G(0.26) extra as I broke those quite often. I found the manufacturer for Fender picks, too and would get 2-3 gross at a time, but I can't remember the name of the company.
