Grolier Life in America Cards

Are these Grolier Life in America readily available in bulk?  I wouldn't mind getting the entire set of 2,600 cards if they can be had for a low price.  Why?  I would enjoy reading them and I like the photos and design.

These cards are quite similar to Sportscaster cards.  I need to do some research to see how many track and field cards are in the set.  If the set is too much money, I certainly plan to get the track and field cards.

If you have any information on these cards please let me know.
