I would do some research on the issues first. Find out what the current value is for their condition. If they are the Golden Age books and in Mint condition you could be looking at a lot of money selling individually.
Me personally ,no. Since my interests in comics is very limited. As for the store I would contact them. They may be interested in purchasing all or some depending on condition. You may try selling on E-Bay if they are not interested.
