Pringles is giving away free speakers that fit a Pringle can for purchasing 4 cans before 10/31/11. This mod improves the sound and tilts the speaker to aim at the listener instead of straight up or laying down. Free, detailed, instructions are here.
Update (June 28, 2012): Pringles is running the promotion again this year, only it looks like the speakers are red instead of black. Just purchase four Super Stack cans between May 15 and October 31, 2012 and send them your receipts by November 30. The details are here: http://www.pringles.com/current-promotions
