I have books for O Chem, Physics 20 series, Humbio Core, Psych 1, and Boy's Psychosocial Development. If you are a premed or humbio student then you know these courses are very popular/required and the books are very expensive. I am selling them now in the hopes that some underclassmen will want to buy the books now to get a discount and save them for next year. Prices will definitely be higher when school starts. Most of the premed books are over a hundred dollars and I am selling each for $50, they are in perfect condition (all look brand new except for the O Chem) and have no marks or highlighting in them. First come first serve. Thanks guys.
