Visit StartSampling.com for Free Samples, Free Magazines and More

A good site to sign up for is StartSampling.com. The site offers many sponsored giveaways. You'll see offers for samples (pain relievers, cereal, etc.), coupons, magazines (often full year subscriptions).

I always recommend before signing up for anything like this on the internet (ad supported) is to sign up for an email account that you don't really care if it gets spammed. I've been using a Hotmail account for years now and I actually don't get to much spam in it; I think Microsoft has some good junk mail filtering for Hotmail.
