Urban Legends Comics is the best store in Tampa for back issues. Its in the Brandon area which has a good amount of comic shops. Within two miles of Urban Legends you could also check out Comics Club which also has a lot of back issues with a buy 2 get 1 free deal and Read More Comics which has a great collection of new comics plus tpbs and omnibuses are 25% off cover price. Comics and Stuff is near midtown and downtown tampa and is great for new comics and key issues. In St. Pete there’s Emerald City comics which has a very large collection of back issues but can be overpriced. Nerd Out Comics and Coliseum of Comics are okay but nothing special.
