Reddit reviews Rocks: My Life in and out of Aerosmith

You're missing the point... Don't look at the 3rd party listing prices, look at the main page, where it shows the list price. List price for that book says it's $28.

When it comes time to replace books, if nobody on Amazon is selling one, I doubt that the Library is going to send someone to scour yard sales and thrift stores to find a replacement. They're going to charge you the list price to replace a book.

How about 48 cents for a new copy of one of the books in question?
