Got this via pureprofile, valid for new & existing members.
Terms & conditions apply (http://www.hotelclub.com/hotel-specials/discount/terms.asp) including a minimum $270 booking which makes it not a huge deal but if you were going to pay that anyway then could be worth it for you.
Warning when booking with Hotel Club -
They charge a cancellation fee regardless of the time of cancellation.

If you wanna be flexible or if you think you will find a better fare later, avoid hotelclub
