www.MINT.com - Try it!

http://www.mint.com/

We've only been using this site for a couple of weeks, but so far it is one of the easiest and best financial management tools we've used and we love it! It literally takes only a few minutes to set up, and is far less involved than Quicken or Money. Essentially you link your online accounts (bank, credit cards, investments, etc...) and mint brings all your details into one location and automatically assigns your purchases to categories based on the place of purchase.

Once your accounts are linked, you can easily trend your spending, your investments, and set up budgets and goals. You can even compare yourself against national, state, or city averages.

And best of all, it's free! They make their money by suggesting ways for you to save (To lower your mortgage, refinance with...)

Thanks to our friends Corey and Wendy for recommending the site!
