Missing Homework pages!

I just found out that if I get a Roku I can get all my regular channels plus a few more. I am just finding out that the homework I have to do for my accounting class includes a page that is missing from the book I order from someone on ebay. I would have to send it back or forfeit the money. If she makes me forfeit the money I will leave a neutral comment stating that I was missing vital pages from book and was forced to repurchase. Also, I located another one on ebay with all the page there but just a little worn. I will bid or try to buy that one. Superbowl is starting now so I will go to a channel to find that or something but I have to do my  homework first of all, at least what I can do.
