I think it might depend on the offer as well. I'm probably the same on most things. But AppSumo has a similar "Free Deal" on their site where you get access to the video/product after tweeting about it. Since I may actually be interested in the offer most times, I'm usually pretty happy to do it. I know that I'm going to get value out of it and, by helping advertise the site, I'm helping them continue these offers in the future.
