I am a prof and never adopt a new edition until it at least one year old so students can buy it used. If it's brand new, they do not have any options and have to pay $120-150 for the new text. When I do this, I get some serious resistance from the bookstore. They call me like 3 times before the order is filled. "Don't you know there is a new edition? Would you like us to order the new edition? I can't guarantee that I can get enough copies of the old textbook to the bookstore and some students might not be able to get a book." My response, is "Yes, I know there is a new edition. No do I not want the new edition. Students know how to order books on-line."
I taught first year Physics for a year recently at a Community College, and was asked by a couple of students on the first day of class if they would need the book during the first week. That puzzled me, until I found out the bookstore wouldn't tell them what book was needed until the day before class, and they wanted to order it for $17 on Amazon instead of $80 from the bookstore. I told them that was a great idea, and they wouldn't need it that soon. I remembered way back when in Engineering school used textbooks were hard to come by, most people kept them as references, so I felt badly for them.
On topic, at work our receptionist had to buy a new washing machine, and spent about $1000. The thing never really worked right, and after multiple visits from a service person, she bought another, more reliable "old style" top loader, from another place, which has worked fine. I suggested she fight to get the company to take the first one back, which the service guy also recommended, but she just finds it "too stressful" and won't bother. I then suggested she have the girlfriend of a son, who apparently doesn't mind that kind of thing, do the arguing for a commission, but she didn't want to bother them either. She is, however, trying to look for another part time job to supplement the receptionist thing, because she needs the income, and isn't too many years away from retirement. . .
