Yeah, wrt shelf life, who knows for certain ...I was just postulating. But that's my story and I'm stickin to it
FWIW, I've ordered strings from Stringsandbeyond for many years now. Competitive pricing, really great folks there, and at least a few times a year offer free shipping with
any order (where normally it's free shipping only with orders > $35). I've not bought strings elsewhere in over a decade
