Do you want a value for money MBA, or an inexpensive one? The outcomes are different from different MBAs. A higher quality programme will produce a much larger lifetime increase in earnings while a lower quality one might not accelerate your earnings at all. Programmes like Manchester and the Euro*MBA are actually very inexpensive compared to full-time MBAs at the same schools.

You pay for what you get. An inexpensive program might be a good idea in the short run, but if you're looking for more extensive value - like career placement support services, robust alumni networks, etc., you're not going to find that in an inexpensive program.

I think that in any case, you should look for a program that mixes in-class sessions in with the online structure. The depth of the learning experience and networking you'll get from in-person interactions is much better than something purely online.
