Amazon Prime's $20 Off $30 Grubhub Code Stacks With the Amex Gold Dining Credit
September 27, 2026

Update: The DEALS20 promotion ended October 5, 2026, and the code no longer works. The Amex Gold dining credit still applies to Grubhub orders every month, so the stacking tips below still work with any current Grubhub promo.
The content on this page is accurate as of the posting date; however, some of the offers mentioned may have expired.
Amazon Prime members could take $20 off a $30 Grubhub order with promo code DEALS20 from September 15 through October 5, 2026. That offer has ended. The American Express® Gold Card monthly dining credit still works on Grubhub, so you can pair it with the next Grubhub or Amazon promo the same way.
The Grubhub Offer (Expired)
- $20 off orders of $30 or more on Grubhub or Seamless with code DEALS20.
- Activation was required through the Amazon offer page before ordering.
- Pickup and delivery both qualified.
- Ran September 15 through October 5, 2026. The code no longer works.
This was one of the warm-up promotions ahead of Amazon Prime Big Deal Days on October 6 and 7, 2026. Prime membership also includes a complimentary Grubhub+ membership, which removes delivery fees on eligible orders, so the delivery route is not automatically the more expensive one.
Monthly credits expire whether you use them or not. Kudos keeps every credit on your cards in one place so none of them quietly reset. See how perk tracking works with Kudos Premium.
Stacking the Amex Gold Dining Credit
The Amex Gold carries up to $10 a month in statement credits at five partners: Grubhub (including Seamless), Buffalo Wild Wings, Five Guys, The Cheesecake Factory, and Wonder. Enrollment is required, the credit resets on the first of each month, and anything unused disappears rather than rolling over. The cap is $120 per calendar year per Card Account, not per card, so additional cardholders draw from the same $10.
When Grubhub or Amazon runs a promo code, the order matters: the code comes off first, and the Amex Gold credit covers up to $10 of what's left. During DEALS20, that meant:
- $30 order, minus $20 from the code, left roughly $10.
- Paying with the enrolled Amex Gold applied the $10 monthly dining credit to that charge.
- What was left was taxes and any fees the credit didn't fully absorb.
Be realistic about the last line. Taxes and service fees ride on top, so this is close to free rather than exactly free, and how close depends on your state and the restaurant. The credit applies to the amount actually charged to the card, so a slightly larger order simply means you pay the difference.
Two exclusions worth knowing before you order. Gift cards and other non-dining purchases do not qualify, so buying a Grubhub gift card to bank the credit will not work. And only one statement credit is issued per transaction, so splitting an order into two payments does not get you two credits.

The Amex Gold dining credit resets each month and does not roll over. You won't miss out on another monthly credit with Kudos, though.

How to Stack It, Step by Step
- Enroll the Amex Gold dining credit first. Log in to your Amex account, open Benefits, and select Enroll Now. Only the Basic Card Member or an Authorized Account Manager can enroll, and an unenrolled credit does not pay out retroactively.
- Find a current Grubhub promo code in the Grubhub app, your email, or through Amazon if you're a Prime member.
- Build an order that meets the code's minimum, which is usually measured on the subtotal before taxes and fees.
- Apply the code at checkout and confirm the discount came off before you place the order.
- Pay with the enrolled Amex Gold. The statement credit usually posts within a few days, but Amex allows itself up to eight weeks, so do not panic if it is not immediate.
The order matters. Enrolling the credit after you have already paid is the most common way people miss it.

What to Do If a Grubhub Promo Code Won't Apply
Some people hit errors applying Amazon-linked Grubhub codes like DEALS20, usually when their Grubhub and Amazon accounts are linked in a way the promotion doesn't recognize. The workaround that has been working: unlink your Grubhub account, then use the Amazon login option at Grubhub checkout instead of signing in directly. The promo code generally sticks after that. If it still fails, do not place the order and assume it will be fixed afterward. Promotional discounts are applied at checkout and are not usually added retroactively.
Common Questions
Is the DEALS20 Grubhub code still available?
No. DEALS20 ended October 5, 2026. The Amex Gold dining credit is ongoing and resets each month, so you can still use it on any Grubhub order.
Which restaurants count for the Amex Gold dining credit?
Grubhub (including Seamless), Buffalo Wild Wings, Five Guys, The Cheesecake Factory, and Wonder. Purchases have to be made directly with the partner at a U.S. location, so a Cheesecake Factory inside a hotel or airport may not trigger the credit.
Can I use the Amex Gold credit more than once this month?
No. The dining credit is capped at $10 per month, up to $120 per calendar year across every card on the account. Once you use it on a Grubhub order, it is spent until the first of next month.
Does Seamless count?
Yes. Seamless is part of Grubhub and is treated the same way by the Amex Gold credit.
Does every Amex Gold card qualify?
No. The credit is for U.S. Consumer Gold Card accounts. Traditional Gold, Senior Gold and Classic Gold are not eligible.
The Bottom Line
DEALS20 has ended, but the stack still works. Enroll the Amex Gold dining credit, apply whatever Grubhub promo is running, and pay with the Gold.
The credit resets on the first of each month whether you use it or not, so there is no reason to let it sit.
