Checkout walkthrough
How to apply a Grammarly code
- 1
Pick a code that matches your cart
Filter by intent (renewal / student / free trial) above. We rank by checkout success-rate first, headline discount second.
Reveal copies it to your clipboard.
- 2
Open Grammarly
Use the Get deal button — Promu forwards you with our tracking ID so attribution lands here and not with a competitor. New tab opens.
Watch for the URL ?promu_tid=… on grammarly.com.
- 3
Paste at checkout
Most Grammarly flows show a "Promo code" or "Add coupon" field on the cart page (sometimes hidden under a "Have a code?" link). Paste, then click Apply.
On mobile the field is usually below the order summary.
- 4
Confirm the discount appears
The new total should drop before you reach the payment step. If nothing changes — flag the code; we re-verify within 24 hours.
Screenshot the discounted total for your records.

Editor's combo tip
Stack up to 65% off off at Grammarly
- 1
Sign up for the email list — Grammarly sends new-subscriber 10-15% off automatically — wait 24h before checkout.
- 2
Apply the Promu code — Stack on top of any auto-applied promo. Storewide codes usually combine cleanly.
- 3
Check membership / rewards — Grammarly's loyalty program adds another 2-5% per purchase that won't conflict with a code.

Code applied without a fight
I'd been burned by other coupon sites — this one actually worked on my Grammarly cart. Discount showed up before I hit pay.

Saved $60 on renewal
Was about to auto-renew at the full price when I checked the renewal codes tab. Saved about half. Will check Promu before every renewal cycle now.

Took two tries
First code was expired but the second one applied fine. Editorial team flagged the broken one within hours so 4 stars not 5.

On Promu, Grammarly maintains an editorial trust score of 4.6 / 5 across 14,200 ratings, with a verified checkout-success rate of 84% across our active 3-code archive.
Shoppers typically reach this page after searching "grammarly promo code", "grammarly discount 2026" or "is there a working grammarly coupon?" — and the short answer is yes. Below you'll find the 3 codes our editorial team has hand-tested on real grammarly.com carts within the last 48 hours, sorted by checkout success-rate first, headline discount second. We separate first-time from renewal codes because the two don't behave the same way, and renewal pricing is where most software buyers quietly lose money.
Grammarly has been listed in Promu since 2024-01. Promu is an independent affiliate publisher and earns – commission on completed referred sales — commission is paid by Grammarly, never added to your cart, and does not influence the order of codes on this page.
