Eat some Pringles, get a free can speaker
If you like Pringles potato chips you can get yourself a cool gadget for free just by saving and sending in your Pringles receipts. As part of their "Get That Summertime Feeling" promotion, they will send you a cool speaker made to fit into the top of a Pringles can. The speaker can be attached to an mp3 player, smartphone or other device and will work without a can too, but you'll get better bass sound when using a can. The more chips you eat, the deeper the bass! Seems like this would be a good gadget to take to the beach.
To get your free speaker just purchase any four Pringles Super Stack cans, download the pdf form and send in your receipts. The offer is good from April 15 to October 31, 2011, while supplies last.
