Send away for a free Pringles Speaker Device with purchase of four Super Stack Pringles cans

Need to rock outside with just you, your music, and your Pringles?  Purchase four Super Stack Pringles and mail your receipt in, and you will receive a free speaker device that fits on your empty Pringles can (so be sure to save at least one can.)  From the press release:

The speaker device is designed to fit onto the top of any can of Pringles, and uses the empty can to amplify sound when attached to a personal MP3 player or similar music device. 

This odd (and unique) program runs until October 31.  The form, which you can download, is available at Pringles.com.
