How I become the owner of three of the same book for $40

Once upon a time a girl named Wendi checked a book out at the library that looked like this:

She laid it on her bed. 

Then she couldn't find it.

She looked and looked and looked. Finally she went and talked to the librarians. This particular book would cost her $30 to replace plus a $10 processing fee.

FORTY BUCKS.

So Wendi ordered a used book off of Amazon for $5. She brought it into the library. The librarians were very nice, but said that it couldn't be used because the book cover was torn.

So Wendi went and ordered another used book off of Amazon for $5. She brought it into the library. The librarians were very nice, but said that it couldn't be used because the book was from another library, and they were unable to cover up old library stickers. 

So now Wendi had spent $10. She had two of the same book. However, she didn't have the one book that the library was requiring. 

A few more weeks passed, and she finally decided to pay for the missing book. She was able to talk the library into not charging her the $10 processing fee since she had already spent that at Amazon. But she still had spent $30 for the book plus $10 on the two books that wouldn't work.

FORTY BUCKS.

Fast forward a few more weeks. An intensive cleaning behind her bed revealed the long-lost book. 

Wendi had found the lost-lost book. 

(And to answer your question, no, the library could not reimburse her for her error. The processing had already taken place.) 

And so now, Wendi has three of the same book. They cost her FORTY BUCKS. But she has three of them which makes her very proud.

Or frustrated.

She isn't sure.
