does the theater have a discount day?

Select movies and times

This theater has two discounts. Monday 25% candy when you purchase tickets with your RCC card. Tuesday is for 50% off popcorn when you also purchase tickets with your RCC card.

I believe they do on Tuesdays. I could be wrong. I know the Farmingdale Multiplex around the same area does have discount Tuesdays.

Mondays they have 25% off on candies and Tuesdays 50% on popcorn. You must have a regal card though which is free.

Summers has dollar movies on certain matinees

I don't think the major chains on LI have Tuesdays as a discount day anymore. They do in CT, and i think Elwood does as well. If you like movies a lot, check out MoviePass.
