According to that 'Bon Jovi Encyclopedia' book by Neil Daniels...

Bon Jovi - 2 million (at the time)
7800 - 1 million (at the time)
Slippery - 26 million
New Jersey - 18 million
Cross Road - 20 million+
Crush - 9 million
Bounce - 6 million
Have a Nice Day - 7 million
Lost Highway - 4 million

Blaze of Glory - 6 million+
Destination - 3 million

There are sources online that say Keep the Faith sold 12 million and These Days 11 million. Then one would assume The Circle sold about 3-4 million, as well as the Greatest Hits. Also you would include about 1-2 million for Richie's solo stuff.

Then there are a few different sources that say Slippery sold 28 million, Crush 11 million, debut 3.5 million and Fahrenheit 2.5 million. At the same time though some would say HAND and Bounce didnt sell that many.

Adding all that up you get something between 128-143 million. So 130 is about right.
