Denny's Coupons in September 2026

Yes, AARP members get 15% off their entire check at participating Denny's locations. According to AARP's website, the discount is capped at $10 per visit and can't be combined with other offers. Some exclusions to certain menu items, like the Everyday Value Slam and alcoholic beverages, also apply.

To redeem, present your membership card with your check when dining in. For a pick-up order over the phone, mention your membership number instead.

When choosing between the AARP discount and one of their seasonal promotions, keep in mind that their coupons from this year also max out at $10 in value, albeit with a $30 minimum order requirement. This makes the two roughly equal. For smaller orders, a percentage-off promo code or a seasonal bundle can give you a better value.

Denny's doesn't offer a year-round military discount for the whole chain. Instead, they run a Veterans Day promotion each year. This gives active-duty military members and veterans a free Original Grand Slam breakfast on November 11. To claim it, show a valid military ID in-store on that day. The offer is only good at participating locations, so call your nearest store ahead of time to make sure it's available.

Since this is a once-a-year promotion, we don't suggest planning regular visits around it. Other offers throughout the year are easier to access and often give better value overall.

Free delivery is offered as a limited-time promotion. Based on Denny's official Facebook posts last year and Denny's Myrtle Beach Instagram activity this year, these offers don't follow a set schedule. However, they often apply to all orders without a minimum. Keep in mind that free delivery applies only to the delivery fee itself. Other fees like service fees or third-party platform fees will still be incurred.

However, if the promotion is unavailable in your area and the order is small, consider picking up your food instead. If dining in is possible, you can also go for that since it skips all delivery-related fees.
