May 11 update: Because they experienced technical difficulties during last week's freebie, Cadbury has relaunched it! This freebie will run until all 15,000 bars have been given away.
Originally posted May 4: Over on their Facebook page, Cadbury is giving away free chocolate bars this week! Right now, you can show a friend some love on their Facebook page by sending them a chocolate-gram.
