Which school are you thinking? I know many well established universities offer online programs. However, if you are planning one of the many schools that have popped up over the years that offer the online degrees, then I think it will be a waste of time and money. Your MBA, more so than other degrees, really matters on where it's obtained from. Most people want to go the online route because they think it will be easier (which it's often not). If you are really wanting to do it, there are plenty of programs that cater to people that work full-time. Both the U and Westminster offer these programs.
