We rounded up this week's dining freebies and discounts in New York and New Jersey for the second week of October. With code SCARYGOOD, Shake Shack gives a free Chicken Shack with orders of $10 or more through the 11th, then switches to a cheeseburger (12th–18th) and a ShackBurger (19th–31st). Through the 18th, Grubhub offers buy-one-get-one deals on Pizza Hut Personal Pan pizzas and Marco's small pizzas, and Panera adds a free bakery item to delivery orders through the 11th. Taco Bell's $4 bundle, a free Snacker with KFC app orders and 7-Eleven's two pizza slices for $5 are also valid this week.

With dining out costing so much this fall, a wave of promotions in New York and New Jersey this week can turn a meal into a freebie once you download an app and enter a code. Most require only a chain's app or delivery-app membership. We have listed them starting with the ones that expire soonest. All apply at participating locations only, so check in the app that a deal applies before you order.

Shake Shack's Halloween promotion, "Scary Good Deals," runs all month in October.
