The Good websites usually require you to Refer Friends or Complete Offers, and often both.
The Bad websites usually tell you that you can earn a laptop for something like reading email. Then they spam you until your inbox is thoroughly flooded.
Of the Good websites, the following website is among the best:
The reason being that you are only required to complete ONE offer (instead of say, 13), and there is always at lease one completely FREE offer available. What's better, you can basically choose whatever gift you want. You are not automatically required to earn an iPad, or a MacBook (items that inevitably require more referrals). Rather, if you want to go it easy, you can select a "not-so-hot" item (say, a bread maker or a vacuum). This way, you can win things for as little as two referrals!!
