Site That Finds And Integrates Coupons With Low Pricing?

We see tons of variations on the meta-search concept for E-Commerce, but this site seems to have hit on a truly practical combo: An engine that finds the lowest prices and simultaneously finds relevant coupons and then integrates the two.

The site,, says its display will include redemption instructions and expiration dates and claims to only show "name brand merchants who have solid customer service ratings." How PricesandCoupons defines that last part is where my eyebrow raised, but the concept still has some serious potential.
