I don't begrudge them anything they get but the perks are more than a few bottles of Philosophy. Some of the hosts have talked about the big boxes of items arriving on their doorstep from vendors/lines. I think many times, if not all the time, they get the TSV for free. But that is all part of their job and more power to them.
I know people who work at various retail stores and get the good merchandise as soon as it arrives or they buy things as soon as they are marked down. When I worked in a hair salon, I never paid to get my hair done and got all my hair products at cost. That saved me a ton of money.
That being said, I think the hosts "fib." Some hosts will say they aren't allowed to order anything new prior to their show, that it has to be presented to viewers first. Then you have a host claiming she bought all kinds of new stuff before she came on air to make sure she got it. It's all a sales tactic.
