Simple is good. And that’s part of the reason why I like PriceYeti, a new site that tracks prices for anything sold on the Internet. (The other part is the site’s adorable mascot, above!)

Registering is not required to use PriceYeti, though you have to share your email address so the site can alert you to price drops. Just plug in the url (website address) for the item so PriceYeti can find the item’s price.

You can return to the site to add items to your “watch list.” I entered three cashmere sweaters for a price comparison, one from J.Crew (full-price, $145), one from Nordstrom (on sale for $58), and one from Macy’s (on sale for $90).

PriceYeti aims to be your shopping cart for the entire Internet so it can track prices for plane tickets, event tickets, houses, and services – as long as the item has a barcode and a url (website address). If you want to make your wish list private, set up a password. The site makes money when users click through from the site and purchases an item.

The site’s design as a Twitterish feel to it, though it has no connection to the popular social networking site as far as I know. PriceYeti is a privately funded start up from Seattle. Read a little about the four guys behind PriceYeti.
