The survey also found that fully 3/4 of students reduced their entertainment budget so they could pay for textbooks, while 57% gave up their spring break trip. What surprising (to me, at least) is that 45% have had to cut back on food in order to pay for textbooks.
The students were also willing to go to some extreme measures if it meant they could avoid carrying textbooks. A third would rather take 8am classes every day for their entire college career rather than carry textbooks around, and about the same number would give up their Saturday night plans, if it meant no more physical textbooks.
And yes, a quarter of students claimed that they'd give up sex if it meant they wouldn't have to deal with physical textbooks.
