5points has the biggest selection in atlanta for any fitted. There's about 6 stores all around each other that have atleast 50-80 styles to choose from.

There's a mall in dekalb that sells them for around $20 for most of the fitted New Era and Cooperstown(american needle) hats. Westend Mall, which is in the hood, has hats and official Jordan shoes for $10 (fitted hats) and $70-80 (jordans).

There's a hat store right across from that little park off of peachtree street (right by 5points sports) that has an entire wall for any taste you might have. That's where I get most of my RARE fitteds for $30 rather than the $45/$60 other stores have them at.
