I was looking up places to buy Dr. Pepper down under, and I came across this story involving the ever charismatic Axl Rose, enjoy

In a unique marketing strategy, Dr Pepper entered a dare of sorts between themselves and Guns N' Roses front man Axl Rose. They stated that if Axl Rose managed to release his new album, Chinese Democracy, in 2008, they would give everyone in America a free Dr Pepper. Chinese Democracy, which was in the works for fourteen years, was released on November 23, 2008.[23]
Dr Pepper put a coupon for a free can on its website, but, the website to download the coupon was inaccessible throughout most of the day.[24] In response to the difficulties, the option to phone in a request was made. After dialing 1-888-DRPEPPER the caller was greeted with an acknowledgment of the technical problems with the website and the caller was then allowed to enter their name, address, and email address to receive their free Dr Pepper. Due to the website issues, the offer was extended until 6 p.m. on November 24, 2008, yet several people still experienced problems registering.[25]
Axl Rose threatened to sue the soft drinks manufacturer for a public apology, and undisclosed damages, alleging that it failed to honor this promise. No suit was filed.
