What determines the price of the books? It has taken me several years to collect all but two of the Animorph books through thrift stores and yard sales. I finally decided to just go to Amazon and by the last two I need.
I looked through the list of Animorphs books, which are listed between 1 penny and five dollars. Except for the two I need #51 and #53 which are $16 and $12 bucks... What the heck? Even the last book #54 is only 34 cents.
I would have figured that one would be the most expensive/hardest to find? Other then the fact that there the last two I need, why would their price be so much higher then all the other books? Are they rare or particularly good books or something?
