My first guitar in 15 years, and one question.

Played guitar and bass when I was a teenager, but got rid of my stuff in my 20s when money was tight and I wasn't playing much. Been feeling the need for a creative outlet recently so I went a few towns over to a used music shop and grabbed this beauty. I've always loved Ovation guitars, the round back profile feels more natural to play than a standard dreadnought style. Spent a bit more than I was hoping when I walked in but I'm very happy to have something to play again.

I do have a question for the community here; where do you buy strings and whatnots online, that's not amazon or guitarcenter? I live in rural BFE and there are no music stores within 50 miles of me or else I'd go to one of those.
