Kotobukiya is a grocery store that carries a reasonable selection of manga. There is significant overlap in manga and magazines between Kotobukiya and Sasuga; however, their selections do differ. Kotobukiya gets their weekly manga by ship, so they're a couple weeks behind Sasuga (great when you've missed an issue at Sasuga).
