I went to hotels.com and received the following message. I'm new to slickdeals so I hope I'm posting this right.

* Valid towards a new hotel-only booking of a hotels.com Price Match Guarantee hotel for travel between February 20, 2009

This still works, I was able to book an already deeply discounted hotel in New York and get an extra 10% off.

Thanks!
