When you say the Ross Park Mall store are you talking about Steel City Collectibles????
There is also one off of Greentree called greentree sports cards i think and he is cheaper on some boxes but has alot of the magic cards and those guys in there off and on. Really strange hours too and sometimes just randomly closed.
