To buy or not to buy, that is my question..

A local store has the Groo Dynasty, Festival, and the "A" one. I already 
have all the Epics, so is it worth buying? Is there something more to 
them besides a straight reprint? They are being sold at a discount. Could 
someone let me know if I should buy these for a reason other than just 
because I don't own them yet.
