Where to Buy Acoustic Guitar

My 11yo niece has started learning the guitar. Her dad asked me where he could buy the acoustic guitar. I should have ask him to Order online here. Will give him the link to this post. Anyway, I tried teaching my own 11, 10 and 8yo how to play the guitar since their cousin is already learning. You know, peer pressure. Unfortunately, they can't bear the pain while holding down the chords with their lil fingers. My fingers hurt too. No longer "seasoned" coz I have not been playing the guitar for years!
