Hotels.com offers regular room promotions, deals and discount codes. The discount codes proved to be very useful, to lessen my booking cost but of course, with the code, I can't accumulate the nights for a free night stay. Pricing does fluctuate, like many other sites, so users would have to check properly before booking. I've used it in recent trips to Thailand, booking went through well but do note, hotels do have their own deposit / room policies and would still require a credit card / cash deposit.
In all, it's legitimate and a good site for room bookings.
