simplydop3 replied to your post: I paid $25 for an entire semester of textbooks.

how does one do such a thing?

I’ll put it this way: If finding things online was a super power, I’d be in X-Men for this. The $25 I paid was to a person to let me share her book that she paid $50 for. The other three (total retail value: $370) I was able to find pdfs and .djvu files online. Free.
