The people that brought you the free iPod, free Playstation Portable, free handbag, and free iPod Shuffle are at it again with a new offer. This time it’s a free digital camera.

Among the cameras is a Canon Powershot S70 7.1 megapixel which retails for about $500.

Like all of the free electronics offers, you have to sign up and complete a marketing trial (several are free if you cancel within the trial period) and get friends to do the same.

Whereas the iPod shuffle offer requires only three referrals and the Playstation Portable requires five referrals, the digital camera offer takes ten — but then the iPod Shuffle retails for $100 and the camera is five times pricier.

Once you’ve entered your email address, you’ll be asked whether you want to participate in several offers. Choose not to, as the offers won’t get you anything. After several optional offers, you’ll be taken to the main free electronics page where you’ll have the chance to complete your own marketing offer as well as refer friends.

You could apply for a no-fee credit card, or sign up for a Netmarket trial for $1. I did the Netmarket offer when qualifying for the iPod shuffle, and cancelling with them was easy.
