Sign up for swagbucks and install the toolbar. With this toolbar, you can use swagbucks' search engine, which periodically awards you for using it with $wagbucks. Once you have 450 swagbucks (which never takes long with the amount of searching I do), you can trade them in for a $5 Amazon gift card. I do nothing but typical searches and I get gift cards to buy kindle books with!!! You can apply as many as you want to your account, so even if you're yearning for that $9.99 ebook, you can still get it for free and the author gets more sales! It's a win-win.
You can use my referral link above to get 30 swagbucks right off the bat.
