I'm always wary of these. The losing of stay credits, points, and elite benefits, plus the fact that Expedia's rates are usually higher (can't use corp. discount(s), AAA, BRG's, cancelable rates, etc.) far offset the ~$20 or so you save.

I know Expedia has their own BRG, but I try and avoid 3rd party sites, so $50 Expedia credit has limited value to me.

Maybe this would work for something like a 1-night Bed-and-Breakfast, but it's not worth it to me to lay out money in anticipation of using this deal.
