Once upon a time I got a gift certificate for Grüv. Eclectic list of recently released CDs I desired in hand, I went into this trendy, locally-owned music store hoping to walk out with a bunch of great music. Well, Grüv has a wide variety of stuff.... but alas, none of it was what I was looking for. Am I that unique? I never thought so.
Oh, also I was slightly annoyed at their policy with gift certificates. I had a few bucks left on my certificate after finding some stuff I wanted after all (but that wasn't on my hot list) and yet they couldn't give me change - so if I ever go back (doubtful) then I'll have $2 or so credit.
