Lunchbox has a great selection of new and used records. Their prices are comparable or lower than most other shops I've been in. Their twitter updates are very helpful, since they tweet their just-in used LP's. They ave a lot of different genres represented, and I know it's menial, but their labeling system is very helpful when sorting through thousands of records. I definitely will be a regular at this place.
It's really good to know that Charlotte has record stores like this. It reminds me a little of the pre-2004 Manifest.
Parking can be tough, back of the building is best or across the street in the CVS parking lot is your best bet.
