Find the highest hydrogen peroxide content you can find, that's what my dentist said. That being said, I'm in love with Crest Whitening Strips-Supreme. You can buy them full price at the dentist, or get them half off on eBay. Also, I find that for some odd reason, flossing makes my teeth whiter! Plus using Listerine also helps. For a more affordable whitening method, use one of Crest's whitening toothpastes or Listerine's Whitening mouth rinse. It won't give a fast result like in the dentist's office or even the strips, but it'll take you a few shades whiter.
