Is this a good deal for TPR books?

Please help! I am trying to figure out the best buy for the following five TPR books. The seller wants $80 for them.

Here they are:

5 Brand NEW Princeton Review class books:

1)Biological Sciences Review
2)MCAT Tests A-D (4 full length tests w/ answers)
3) Physical Sciences Review
4)Science Workbook
5) Verbal REasoning and Writing Review

Is that a good deal or is $80 too much? She had bought them for the August 2002 MCATs.

Thanks for all of your help! Email me at [email protected] if possible.

Thanks again,
Wendy
