Take a look at this site.  I am a member, and have tried out several different products.  You join, then they send you "campaigns" to take part in.  They send you free stuff, you try it then post your reviews and talk to friends and family about it.  So far I have gotten the following free: large Pyrex baking dish, free can of Pam, free tomato sauce, free boxes of cookies, free pizza, free frozen appetizers. free frozen dessert, and much more.  Give them a look.
