Yesterday -- the day the GN'R record hit stores -- Dr Pepper's site was flooded with visitors looking to cash in on the deal. Due to overwhelming demand and several site issues, Dr Pepper has extended the offer until 6 p.m. today; the deal was originally set to expire last night at midnight. Participants have until February 28 to redeem their coupon for a 20-ounce can of the drink.

Dr Pepper had to increase its server capacity and set up a toll-free number (1-888-DRPEPPER or 1-888-377-3773) to handle the demand. So if you couldn't access the Dr Pepper site yesterday -- or completely forgot about the offer -- you still have plenty of time to get in on the action.
