do you really get paid to try free stuff??  

Did you ever try to sign up? I did, I sign for a survey site with junk email. Guess what, They send me a lot of invitation, most of them ask my credit card number. I search on the internet about them to make sure. But, they suggest me not to give my CC numbers to anyone especially on the internet.

I've never been lucky enough to get to try something and also get paid to try out that item as well. However, I do have friends that are in my playgroup that are members of some different survey sites that do let you try out new products and also get paid for the time that it takes you to evaluate the product. However, I've not been able to get accepted onto any of those panels yet. They are very, very difficult to get accepted into.
