That would be a good idea for a store. Specialize in all retro stuff...
Retro games ported to newer systems, retro dvds of old series, t-shirts of retro bands/shows, etc. Even a swap shop for retro items.
The Retrojunk Store, in a mall near you! LOL!
They have a store like in Cleveland, OH called Big Fun. They specialize in all things 70's, 80's, and 90's (clothes, toys, video games, you name it they probably have it). A true retrojunkers paradise. Not to mention they also have an extensive gag and novelty section. Jesus Christ action figures, anyone? ^_^
