Is there any point in doing an online masters?

I have a shitty bachelor's degree from tier 2/3 college that has been a hindrance in getting good jobs. Need a master's degree but full time MBA seems wasteful and expensive, since I already understand the basics of business and have bootstrapped startups from scratch.

Are online MBA or master's programs any useful or helpful? Any recommendations? I'm on a budget, can't spend more than 5-10 lakhs.
