Not unless they've moved Tokyo to the Bluegrass State, Ed. But you're partially right. The above is a typo, and it's an 11 ounce bottle (that'll teach me to squint instead of putting on the reading specs).
So, I'm paying 39 cents/ounce, vs your 59.6. I don't say you're being ripped off, compared to me; just that prices differ based on location, and south Florida may as well be New York in that regard. Nobody down there is offering any bargains, in my experience.
Obviously I didn't do the actual math, just rounded off and horseback estimated. But now that you've done the figuring, and given the geography, do you really consider an 8 cent difference as being ripped off? If so, than you must feel pretty badly about being ripped off to the tune of 20+ cents an ounce.
Anyway, returning to the original issue, there is no reason to cut sesame with other oils. It's a finishing oil, used to provide flavor and sheen, and only takes a few drops to accomplish that. Actually cooking with it doesn't make a whole lot of sense on several levels.
