Price Drop allows you to watch an item's price and it will
email you when the price changes. You can very quickly register
and start receiving emails when the price of an item changes.
How it works
The system is constantly checking and updating the prices as
other people are searching for the same products, and also
checks the prices on a regular basis.
It knows when it last informed you about a particular product and
when it last emailed you, so you won't get bombarded about
a specific product several days in a row.
