Bachelors direct to DBA

[Doctor Who]

First post  and I wanted to ask about online DBA (preferably AACSB) directly from a 4.0 GPA bachelors. Is that possible and if yes what are the cheapest option out there?

Is it better to find a cheap online AACSB  MBA first? Which one?

Is there such a thing as a cheap DBA in the US or should I look at the University in South Africa or any other country that are AACSB accredited? I'm in the Northeast where colleges are expensive AF.

Guidance appreciated. Thanks
