Martini Question For The Masses

Good people, this poor man needs your help:

My wife drinks dirty martinis, just vodka and olive juice. Most bars just pour the juice off the olives. We do the same thing at home, but end up with a jar of dry olives. At the Mansion last week, the bartender had a bottle of olive juice. It makes so much sense. Any idea where we can get it?

I’ve bought it here. Any local suggestions.
