Children's book exchange

pazrana

So I got a letter from a friend to do a book exchange.  It's basically a Ponzi scheme for books.  I send 1 book to the child on the top of the list, move the next child up and add mine to the bottom of the list.  I send it to 6 people and they do the same.  So, you buy one book and should get 6 of them.  Is anybody interested in participating? If so pm with your address, and I'll send out letters to the first 6 people who respond.

 

PS the letter says you will receive 36 books but I can't figure the math on that!
