For the DoorDash deal, you'll have to place an order via the DoorDash mobile app or via the DoorDash website, add a 6-piece order of Spicy Chicken Nuggets to your cart and enter the code, "SPICYNUGGS." No purchase is necessary but a delivery and service fee may apply.
For the Wendy's app deal, you can just click on the appropriate tab in the Offers section of the app.
Wendy's Spicy Chicken Nuggets feature breaded and deep-fried white-meat chicken nuggets with "three different kinds of peppers and savory spices."
A 6-piece order of Spicy Chicken Nuggets normally costs $1.99 in my area ($3.29 for a 10-piece order).
