Tracking the price of The Completer Guide to Mid-range Glazes

Hey,

I don't know if you all know about    Camelcamelcamel.com

But it is a price tracking site for Amazon. You  just put in what you are interested in and it will show the price fluctuations. You can enter a price you are looking for and it will alert you when it happens.

It is amazing to me to see  how they use some algorithm to balance price, availability and demand to vary current prices daily. I have just been watching my two books and thought someone else would find this interesting or useful.

It is just like the airlines and ticket prices. Everyone on the plane gets a different priced ticket.

 I guess that it is like in the old days when you bargained for something with a vendor, only now it is being done by the seller and a computer.
