Treasure Trooper is my favorite - mostly because they've made me the most money! See those pictures? I made almost $150 for filling out some dumb surveys and doing offeres! They mail checks or deposit in your paypal. TIP: search for keyword "email address" or "zip code" - all you have to do is enter your email/zip code! No forms! They're my faves. Open up a new email account to handle all the spam.
Send Earnings is good because it's super lazy. They send you emails, you click on them, they pay you. You can receive money when you get $25. They give you $5 when you sign up, plus referrals, and if you're not lazy you can do the surveys and stuff too. I mostly just do the emails, it's a super easy way to add up money fast (each email is about .02, they send about 2-3 a day.) My first payment just arrived in the mail! It takes me about 2 months to earn the $30 just by answering the emails. TIP: save 'em up and then answer them all in a big bundle once a week - they're less annoying that way and you can see how much your money jumps up!
