Bird on a wire asks, "Priceline now lets you name your own price for groceries. Will people really put up with the hassle?" and I say: Hell, yeah!.
I'm certainly not the coupon-clipping type, (I'd rather throw money at a problem than throw effort at it...) but Priceline really does save you a bundle. And I'm not just saying that to suck up to Bill Shatner.
