Once you download the app and sign up for an account, you’ll automatically join the Craver Nation rewards program. As a member, you’ll get a ton of White Castle promo codes, which will automatically be added to your app as they become available. Some of the past promo codes we’ve seen include:
- 20% off all mobile orders
- $3.99 Chicken Ring Combo Meal
- BOGO (Buy One, Get One Free) on all Breakfast Sliders
- $5 off any late-night Crave Case slider 30-pack from 11 PM to 3 AM
- $2 for 6-piece Chicken Rings
Usually, about four or five promo codes are added to Craver Nation every month, so you can always save on your menu favorites. Some promo codes can be used multiple times, while others can only be used once, so keep this in mind.
