According to WalletPop.com, Dr Pepper's web site appears to be having a hard time keeping up with demand for a soda following the soft drink manufacturer's announcement earlier in the year that it would give a free drink to everyone if GUNS N' ROSES' long-awaited new album, "Chinese Democracy", actually dropped in 2008.Interested fans are being asked to visit DrPepper.com today (November 23), the day "Chinese Democracy" is released in the U.S. exclusively via Best Buy. After registering online, fans will receive a coupon redeemable for a 20-oz. Dr Pepper wherever the drink is sold. The twist: the coupon is only available for 24 hours and will expire on February 28. Repeated attempts by WalletPop.com staff to reach DrPepper.com have resulted mainly in a longtime "loading" message on the main page. When WalletPop.com has managed to get in, the coupon location wasn't immediately clear. It's apparently behind "Promotions" and then "Free Dr Pepper" — but then that page wasn't loading for WalletPop.com either. Then WalletPop.com tried 1-888-drpepper (1-888-377-3773), as recommended to the site by a company spokesman. WalletPop.com called midday and got an operator after a 15-minute wait. The spokesman also said the company was working to add more servers to handle the web traffic — this also around noon, 12 hours into the 24-hour promotion.
