Are you serious????
I've never had to sign up for any offers from them.
I've received a Socicare Electric toothbrush, a Sonicare Toothbrush Sanitizer, Bertolli Tortillina, The Secret Between Us hardback book by Barbara Delinsky (it hasn't even been released to the public yet), plus numerous other items.
All you did is sign up for campaigns, and when the things arrive in the mail, you buzz them to other people and then write up a report or two about what you did to pass the word.
Heck, a friend of mine even got a free bottle of tequila to buzz.
You don't get any money from them at all ... but you get points that you can buy things with, nothing really special though ... or you can donate the points for money to different charities.
