FloFA has Superjets , the security deposit for which is 1million plus in the patois of the people, or 1.4 million if you prefer exactitude's although that takes no account of whether he ordered a job lot.
I do not want to play language police, but the way you wrote your previous rpely it sounded like he would get back one million AND a security deposit.
The correct way would have been to write that he will get back a security deposit of one million plus, or a security deposit of 1.4 million, or a one million plus dollars of security deposit, etc.
In any case, it read like a million and a security deposit, that's why I commented "what one million".
Now it's clear what you meant.
