My experience wasn't quite as in depth as the previous reviewers, so I have no complaints. The store has a lot of instruments, sheet music, reeds, kid instruments (is there any instrument worse than the recorder? I say that with total sincerity as I fear the day my youngest hits the recorder age. My oldest has been there. It was horrid).
I like the ability to go into the store to buy him the reeds he wants (I've done amazon before and clearly I'm not equipped to buy the correct ones as I've bought the wrong ones there). He also needed a flip folder for band camp. I love that the supplies he needed were here, we got a school discount (which would assist with the mark-up prices others gave mentioned). We didn't get an offer for help, but didn't need one.
