ever since the intercontinental BRG free deal
ive been watching it
no its not free but enough of a discount that its worth booking, always having the option to cancel up to a day before should another such free deal come up
example
marriott offers a price match to the lowest price you find plus an additional 25% OFF
in my case a NY 4/5star HOTEL during august booked at marriott for $359.99 plus tax =$415.45 ended up costing me $196.00 inc tax
