Yipit.com aggregates Groupon, LivingSocial, and hundreds of other daily deal sites(including non-location specific ones like Woot). It will filter the deals based on your location and specific interests you have.

Disclosure: I recently started working for Yipit.

Very nice, I had heard of the site but never tried it out. Do you guys manually aggregate everything?

Originally it was all done manually, but we've been automating more and more.

Feel free to send me any feedback. [email protected]

A bit like that comic strip "funny today or not" aggregator.
