I remember McCrory's and Woolworth's, although, I don't think I ever sat down at their lunch counters for anything to eat. When we lived in Gales Ferry, CT, we also had Caldor and Vality. Vality - which I think stood for "Value and Quality" - was sort of a predecessor of Wal-Mart: groceries, clothes, housewares, electronics, etc., all under one roof. I remember spending lots of time browsing their record bins. I bought the 2-LP set of "Saturday Night Fever" there. Vality's was also part of our post-church routine on Sundays which would also include a stop at Spiro's for pizza.
And then there was Zayre's in northern Virginia, which eventually became and Ames... And now it's a Gold's Gym.
