I've been on the Prize Reactor site for a few weeks so far and I've been really impressed with the amount of prizes to choose from. I've not won anything yet but I can see there are new winners each week and the website is all run by a company that seems legit from what I can see. I'm not sure where the $5p/w figure's come from on the other comment as I've never seen any mention of having to pay since signing up. I'll keep entering offers and wait my turn to win something! :)
