Add some Wesabe to your Mint

Wesabe takes anonymized purchase data to manage your finances better and has recently launched a system to help you purchase the same items at other locations. The system seems like it would be a nice mix to go along with Mint.com in an overall financial strategy.

Of course when the system says I should buy at Walmart instead of Target, I'll have to refuse that advice. The next step in these financial systems should start monitoring the social and green aspects of the places you are shopping.
