DealDroid is small application for Android devices that continuously watches for new deals on one-deal-at-a-time sites like BonkTown, Brociety, ChainLove, Steep and Cheap, Tramdock, Whiskey Militia, Woot and associated sites, ThingFling, and SlickDeals. DealDroid runs in the background and produces Android notifications when new items become available.

You can configure how aggressively the software will search for new items, as frequent background updates and keeping the phone awake may decrease battery life a bit. Although, I have not noticed any significant battery drain on my G1 using a 2 minute check interval.
