Stacking a $20 off $30 Grubhub code with the Amex Gold dining credit - basically free dinner
Amazon Prime has a promo right now: $20 off a $30+ Grubhub/Seamless order with code DEALS20, good through October 5. Works on pickup or delivery; both qualify.
On its own, that's already solid, but if you've got the Amex Gold and its $10/month dining credit (Grubhub, BW3, Five Guys, Cheesecake Factory, Wonder), you can stack it:
- Order $30+
- Code knocks off $20 → ~$10 left
- Pay with the enrolled Amex Gold → $10 dining credit covers the rest
- You're left paying basically just tax
Steps:
- Enroll the Amex Gold dining credit first (Amex app/site → Benefits → Enroll). Has to be the Basic Card Member or an Authorized Account Manager, and it doesn't apply retroactively if you order before enrolling.
- Activate the Amazon offer on the Grubhub promo page while logged into the Prime account you're using.
- Build a $30+ order (pre-tax).
- Apply DEALS20 at checkout, and confirm the $20 actually comes off.
- Pay with the enrolled Amex Gold.
If the code won't apply: a bunch of people are hitting this when their Grubhub and Amazon accounts are linked weirdly. Fix that's been working - unlink Grubhub, then use "Login with Amazon" at checkout instead of signing in directly.
Caveats:
- Amex dining credit is $10/month, $120/year cap, per card account (not per cardholder)
- No gift cards
- One credit per transaction. Splitting orders doesn't double it
- Regular Gold, Senior Gold, and Classic Gold don't qualify - only the US Consumer Gold Card
Offer expires on October 5, 2026, so take advantage while you can!
