Wichita, Topeka, Lawrence and Johnson County
Kansas listings fall into two areas about three hours apart. Wichita has the most shops of any city in the state and a real mix: several dedicated sports-card stores alongside Pokémon and Magic game stores. The rest are in the northeast, where Topeka, Lawrence and the Johnson County suburbs of Overland Park and Olathe are within an hour of each other along I-70 and K-10. Overland Park's shops are stronger on sports cards and vintage.
From Johnson County, the Kansas City and Independence shops are a short drive east, over the line in Missouri. A lot of Kansas shops carry vintage. Listings thin out west of Wichita.
