Is your professor banned from telling you where to find cheap textbooks?

It appears that Chegg, an online textbook store, is ruffling the feather’s of restrictive clauses that protect college bookstores from competition. The company has been banned from handing out flyers on campus and has had to cover it’s logo on the traveling bus it takes to tour campuses promoting its brand.

The company is now shedding daylight on the lengths that the college bookstores monopoly protects itself. Reporting a story about George Washington University banning mention of other resources and stores to buy textbooks cheaper, it might make you wonder if your professor is allowed to tell you about cheap textbooks options online or nearby?
