I travel mostly Europe and it happens all the time. Also I have a past working in a travel/booking agency and if you are big enough you can get discount prices from hotels because they know you are going to book them X days of rooms over a month. So, they reduce their margin but gets more exposure/promotion by the travel agency. With flights it's a different thing, but it can happen as well.
