Growth Guys code not working? 6 things to check
Checked October 29, 2026 against the Growth Guys FAQ and my own checkout.
most failed codes come down to where or how they were entered.
- Work through these in order, it takes about two minutes.
- Use the Promo code box, then press Apply. At checkout it sits in the order summary on the right (or below on mobile). Pasting the code is not enough, the discount line only appears after you press Apply.
- Enter it exactly as sent. The vendor's own advice for any code is to check it is entered exactly as given. The code here is DEAL10, letters followed by the digits one and zero. Autofill can add a trailing space, so retype it if it fails.
- Remove any other coupon. Growth Guys allows one coupon per order, so a second code will not stack. Clear the other one first.
- Check you are on the real site. The only official website is growthguys.com. Look-alike domains will not accept a real code.
- Do not expect a code for Bitcoin. The 20% Bitcoin discount is automatic when you pick Bitcoin as the payment method. There is nothing to type. See the Bitcoin discount guide.
- Contact support with a screenshot. If it still fails, use the vendor's live chat or email, and include your cart and the exact error message.
Another 10% option
The vendor's FAQ says that joining its email list gives 10% off your next order. Only one coupon applies per order, so use whichever code you have, not both. If you have the email-list code and DEAL10, they will not combine.
Why coupon-site codes fail
Many coupon pages list codes that nobody ever issued, or that expired long ago, and some generate a page for every search phrase. A useful test is whether a page tells you where the code was entered and when. This site only lists one code, and shows a "last checked" line only after a real checkout check has been recorded.
Ready to order?
Enter the code at checkout. If you copied it, just paste it in the Promo code box in the order summary, then press Apply. It does not apply by itself. Confirm the discount line before you pay.
Common questions
Can I use two Growth Guys codes at once?
No. The vendor allows one coupon per order. The Bitcoin discount is separate and applies automatically.
Where do I enter the Growth Guys promo code?
In the Promo code box in the order summary at checkout. Press Apply and confirm a discount line appears.
Does the code work on sale items?
The vendor's FAQ says you can use one coupon per order, including on sale prices.
