Go to the Swagbucks homepage
Look along the top for Ways To Earn
Click that and select Special Offers
On the Special Offers page, click on the blue box on the right that is titled No Obligation Offers
On the pages that pop up, click skip. Do NOT do the offers.
After you skip a few offers, a page will pop up that gives you a Swagcode worth 1 Swagbuck! (I had to skip about 6 offers)
