OBO Books for sale in Athens, OH

I have three books for three different courses at Ohio University
Bios 103- Human Biology 5th Edition (Runs for about $110 at bookstores) I want to get rid of it for about $45- Most require the 6th edition but Karen Mammone uses the 5th
Psychology 101- I have the 8th edition of the book Professor Hoyt uses (She uses the 9th) but everything is the same except for the order of the chapters. Willing to sell this for about $20
Anthropology 101- (with Duschinski) I have Parallel Worlds (the first book you read in the course) and I will sell this book for around $5.
