From what I've found for ticket prices, showtimes before noon(oaktrees matinee time) cost $6.29 for all ages. There only seems to be a discounted senior price for showings that are not matinee (common ticket prices: $11.01 for adults, $9.44 for children and seniors)
If you're a stubs member (free) tickets on Tuesdays are just $5 plus tax
