These comments made me go back and re-read the site, as I became suspicious. This is the fine print at the bottom of the first page of the site:
"We cannot guarantee that you will receive any of the Offers that you request, as Offers are subject to availability and are often made by other entities. Offers distributed by GetItFree are limited in quantity, and GetItFree reserves the right to substitute sample product based on availability. Offers that are not distributed by GetItFree are monitored by other entities, and we are not responsible if such Offers are no longer available, change, if you do not receive the Offers, if you do not qualify for the Offers, or if any other issues arise."
Translation: We can't guarantee that you will even receive any of these offers. We have the right to substitute what you thought you were trying to get with anything we want. Besides, you might get nothing, and we are not responsible for that. Oh, and you will have to "qualify" for the offer, which means taking a survey or giving us your personal information so we can sell--ahem, USE it as we wish. If we decide to send you something, we might.
