At certain times until the end of June Roamfree will be offering certain hotel deals with $1 a room fee.
All you need to do is become a member of the site and they will email the offers.
Now these guys also now offer cashback which is pretty useless if you are spending a dollar but you may obviously book more
The % they offer appears to be off the sale and not the booking fee - I have checked this on the site but I will email them to clarify
Click thru and you will be take to the sign up page
