I encourage you to do the Searches and the Surveys. I usually earn about a $1.00 a day on searches and in one day alone I earned $5.73 just on the surveys. I do a random search about every 15 minutes or so and you can really do good there. You can earn clear up to 78 Swag Bucks on the Searches.
Referrals work a bit differently than other programs. You do not earn from everything that your referral does. You only earn from the online searches your referral does. You earn Matching Swag Bucks. IE: If your referral earns 50 Swag Bucks doing a search, you earn 50 Swag Bucks. You are limited to only 1,000 matching Swag Bucks per referral. But hey... what the heck... for 700 Swag Bucks you get $5.00 PayPal cash... 1335 Swag Bucks is $10.00. So basically you will earn almost $10.00 per referral. Any resident of the US, the UK, or Canada (except for residents of Quebec) can join.
There are just as many ways that you can cash out as there are ways of earning. Another endless list and they add new things all the time. Here are some examples: PayPal Cash, Gift Cards, Games and Game Consoles, Sweepstakes Entries, Clothing, Books and Magazines, Electronics, Music, DVD's, Baby Items, Jewelry, Posters, even Major Appliances, and tons more. It's almost like shopping at an on-line store. If you want it, I'll bet they have it.
To give you an idea of what the sweepstakes are... right now they you can sign up for a sweepstakes where you can win a Michael Turner (Falcons) Autographed Football or Xbox 360 250GB Console with Kinect or Greg Bennett AV1 Electric Guitar or Gift Cards or PayPal Cash or IPOD and tons more. Another endless list that is added to all the time.
