I lucked out and found a $69.95 book on sale, but when I clicked on their used books, I found goodwill had them on sale: I paid $1.39 for one and 39cents for the second! Praise God! When looking at the used books, make sure condition states "excellent" or "good". I once ordered a book in "fair" condition which had one vital page missing! drats! finally broke down and paid the money for a 2nd copy! Don't be afraid to check out the individual bookstores/buyers - I've had good luck with them! Plus, I always have Amazon to mediate any disputes. Amazon does all the research on finding you the best price!
