Crest Whitestrip samples -- free from Walmart

First impressions are everything, you know.

You want a smile that's clean and white. But those Zoom treatments are a little pricey for this economy. Wal-Mart comes to the rescue once again. It's offering free samples of Crest Whitestrips Advanced Seal, while supplies last.

These new Whitestrips apply directly to your teeth with a new no-slip technology. Just peel them off after 30 minutes and start to see a brighter, whiter smile in as little as three days.

Now that's really something to grin about.
