What are the different types of surveys and which one is better?

You can get rewards by joining www.e-rewards.com you get surveys in your email than you get points with the points you can go to places to cash them in.. This is where i get Best Buy e-cards worth up $25.00 the most. You're best bit is to contact them and ask them how to get placed on their email list contact list and take things from there. I believe someone needs your email to be able to placed on their contacts list. So someone would need to refer you to them than you will start receiving surveys once you sign up etc.
