Subject: Re: What Did You Buy Today?
I bought a nice bottle of Hors d'Age French Armagnac, and a half gallon of Bombay Safire gin.

You did not, unless you bought three 750 ml bottles and salute the Union Jack.
1.75 != 1.875.
I know, real Americans can't do weights and measures math. If miles and gallons are good enough for the US, they are good enough for the rest of the world.
