I do surveys for E-Rewards....and it's awesome. That's how I get all of my magazine subscriptions....free! You have to be a member of one of their cosumers (Blockbuster, Delta, Hertz, etc.), with a valid account number. It may take a week or two before you hear back from them. They have to get approval from whichever consumer you choose. Check it out if you're interested:
If anyone else knows of some legit survey sites, please forward them on!!
