Not the theatre I mentioned before, but another one near me- changed their matinee times to "anything before noon". So, I think there's basically one matinee a day, since the first show-time of the day is 10:00.
We went to go see a show at 4:45P because I thought I'd save $4 a ticket that way. Nope, it was $10.50 already.
But I'm glad I don't live near skyjedi and have to pay his prices.
