My family is moving and I'm finding all kinds of musical items that were bought and never even touched--I have unopened (and still price-tagged) Guitar Method books, packs of guitar strings, lots of books of sheet music for violin and guitar, some of which still have their price stickers. I know I could sell this stuff on craigslist, but seeing as some of these things are completely unopened, are their any music stores that might buy it back? Thanks for any input.
