Simply browse Amazon.com and find a Amazon product you want to track/watch (and get a price alert for).
Here are some simple ways to do this:
As well as the main Amazon price, you can set desired amounts for Marketplace options (new, used & refurbished).
If you have an account and are logged in, you won't even need to enter your email as this will be prefilled for you, making it quick and easy to create Price Spies.
You'll be alerted (via the email you provided) when our system detects a product's price has dropped to (or below) your desired price.
If you have a Slashazon account, everything is prefilled for you so you don't need to keep entering your email address each time you want to create a Price Spy. You can also keep track of all your existing Price Spies, and easily sort and manage them in one place.
If you've already started creating Price Spies for an email address, you can register at any time and all your Price Spies tied to that email address will be there waiting.
Feel free to register now.
