Arby's Coupons in September 2026

The fastest way to save at Arby's is to join Arby's Rewards in the app. New members almost always get a great welcome deal. Currently, you can get a free Classic Roast Beef sandwich with your first order. This is one of the best sign-up bonuses in fast food. The Classic Roast Beef costs about $5, so you save right away just for joining. Once you're a member, you'll get steady deals in the app. Over the past year, we've seen offers like $3 off any order of $15 or more, $1 mozzarella sticks with any purchase, and free small fries with any sandwich. Check the "Offers" tab in the app before every visit. Deals change often, and you may spot a BOGO promo or a discount on a new seasonal menu item.

A few times each year, Arby's runs fundraisers for the Arby's Foundation, which helps youth programs. It's an easy way to give back and get a free treat. Here's how it works, when you donate $1 at the register during the campaign, you'll get a promo code for a free menu item. Past promo codes have included a free small Jamocha shake or a free slider with any purchase. Watch for in-store signs. These fundraisers run for a short time, often during back-to-school or holiday seasons.

Using a coupon is easy, whether you order online or in person. Here's how we do it each week:

For online & in-app orders:

1. Open the Arby's app or website and build your order.

2. Before checkout, tap the "Offers" tab at the bottom.

3. Pick a promo and tap "Add to Mobile Order."

4. The discount will apply to your cart. You'll see the new price before you pay.

For in-store & drive-thru orders:

1. Find your deal in the app's "Offers" tab.

2. Tap the offer and select "Use at Restaurant." You'll get a 6-digit coupon.

3. Give the coupon to the cashier before you pay.

Arby's offers its biggest discounts during major sales holidays. These savings are only in the Arby's Rewards app. Based on what we've seen in past years, Black Friday & Cyber Monday Week is the top week for promotions. The standout offer was 50% off any single sandwich in the app. That turns a $7 brisket sandwich into just $3.50. We've also seen $1 fries and $2 mozzarella sticks with a minimum purchase. Also, watch the app for promotions around the Super Bowl, March Madness, and National Sandwich Day. To get these savings, install the Arby's app and set up your account before the holidays. Any promotions available will be added straight to your account.
