FS: Knight Physics 41 & 43 books

Hi,

I am selling the books for Physics 41 & 43. Both are in usable condition - no marks inside or anything. The covers are slightly worn though.

To be clear:

1. Physics (Vol. 1) by Knight with Solutions Manual, Student Workbook and CD

2. Physics (Vol. 4) by Knight with Student Workbook

$30 each OBO. If you take both, you can have 'em for $50.

Thanks!
