I love love love using old things in new ways, and this is a really fun deal from Pringles. Basically if you save your receipts from buying 4 cans of Pringles and mail them in, Pringles will send you a speaker. You can plug it into your computer, Ipod, or MP3 player. Here is a link to a YouTube video on a guy opening and reviewing the speaker. We don't eat too many Pringles, but I think I'm going to go get some. I'll let you know what I think when the speaker comes in.
