The first freebie site I ever attempted was ipodsweepstakes.com. This site has hundreds of offers for you to complete to earn what they call Pod Points. 1000 Pod Points earns you a new 2nd Generation iPod Shuffle, 2000 points gets you a 2GB iPod Nano, and 3000 points equals a 30GB iPod Video. They actually start you off with 200 bonus points for joining, so you only need 800 more to get the Shuffle. They also run a daily drawing for a Shuffle as well. Each offer you click gets you one entry into the daily drawing.
Point value for the offers vary according to the difficulty of the offer (time, cost, etc.). You will see point values ranging from 5 or 6 points for simply clicking a link and inputting your ZIP code or e-mail address, up to over 100 points for some free trial offers. I have personally received 2 of the Shuffles without ever entering a credit card number or doing a free trial that needed to be cancelled.
Now for a few hints to make this experience quick, easy and enjoyable. First of all, create a new e-mail address to use to sign up for this. The offers you complete will generate a ton of spam that you really don't want clogging up your regular e-mail address. Gmail or Yahoo work great for this. Some offers also require a phone number. Privatephone is great for this. It allows you to create a new phone number and set up voice mail to handle those unwanted telemarketing calls.
Clear your cookies from your browser often, sometimes after each offer you complete. This will help ensure you receive credit for each offer you do. You will also get daily e-mail offers from ipodsweepstakes. Even if you have completed the offer on your personal page, complete it again through the e-mail link, you will very often get credit for it from both sources.
This is a really easy site to do, and is definitely not a scam. As I said, I have received two Shuffles from them and am currently more than halfway to my third, although I think I will hold out for a Nano this time around. Good luck earning your iPod, and if you have any questions, leave a comment and I will be glad to help you out.
