They give away prizes several times a day. I think they do say how many I just can't remember at the moment. And I think it varies on different days. You just have to get lucky and do your search at the right time lol. It's based on google and most folks seem to use that anyway. They give away a lot of movie tickets and some gift certificates. I have seen some cash prizes listed as well. The search page is pretty much like google and works as well. Try it!
