I got a copy of the Pearl from Amazon for $3.98. Right now the cheapest price is $14.98. I can't stand to see you overpay-unless you got the original edition.

I would look here before anywhere else for all the books on above list are available cheap. I have had nothing but 100% satisfaction from this source and I saved bigtime. I hope it is not illegal to say this. I am in no way affiliated with them; it is just my opinion. I will remove this post if it isn't appropriate to mention them by name.
