The Cal Poly bookstore/course catalog might ask you to pay a ridiculous price for a textbook that you already have access to as a student. Try typing its ISBN or title into OneSearch and seeing what you find.

In addition to giving you access to digital download licenses, OneSearch will also allow you to filter by items physically available at CalPoly's or other CSUs' libraries.

I also know that prior years had an opt-out purchasing system, whereby otherwise you would be automatically charged for all your textbooks, so keep that in mind. Hope this helps you not get scammed
