ByHeart Promo Codes & Coupons September 2025

If your ByHeart promo code isn't working at checkout and you see messages like "Promo code not valid" or "Code expired," it usually means the code is either not eligible for your order, has already been used, or is past its expiration date. These error messages are common and indicate specific issues with code validity or timing.

ByHeart promo codes often have rules: they're typically limited to one per customer and one per mailing address, and they come with clear expiration dates. If you try to use a code after it's expiration or if you've already redeemed it, you'll see these error messages. Codes may also be restricted to certain products, order minimums, or first-time buyers, so double-check the terms attached to your code.

To resolve this:

• Confirm the code hasn’t expired by checking the promo’s end date.
• Make sure you’re logged into your ByHeart account, as codes require an account to redeem.
• Ensure you haven’t already used the code or applied it to another order or address.
• Double-check for typos or extra spaces when entering the code.

Pro tip: Always copy and paste promo codes directly from trusted sources and review the code’s terms before checkout to avoid common errors.

No, ByHeart only allows one promo code per order, and you cannot combine multiple codes or stack them with other discounts or offers. This is a standard policy for ByHeart and is enforced at checkout.

When you enter a promo code, the system will only accept the first valid code and will reject any additional codes you try to add. This includes referral codes, sitewide discounts, and other promotional offers—only one can be applied per transaction. Attempting to stack codes will result in an error or the system simply ignoring the extra codes.

Pro tip: Choose the promo code that gives you the best value for your specific order, especially if you have a high-value or first-time buyer code available.

Yes, ByHeart promo codes are typically limited to one per eligible customer and one per mailing address, and some codes are only available to first-time buyers. These restrictions are strictly enforced to prevent abuse.

You must have a ByHeart account to redeem a code, and if you’ve already used a code at your address or with your account, you won’t be able to use it again. Some codes are also tied to specific customer segments, such as new subscribers or first-time purchasers, and won’t work for returning customers.

Pro tip: If you’re not eligible for a code, check ByHeart’s website or trusted coupon sites for other current offers that may apply to your situation.

If your ByHeart promo code isn’t working, it could be due to expiration, prior use, ineligibility, or a simple entry error. The most common reasons are using an expired code, exceeding the one-per-customer or one-per-address limit, or not meeting the code’s requirements (like being a first-time buyer).

To troubleshoot:

1. Double-check the code’s expiration date and terms.
2. Make sure you’re logged into your ByHeart account.
3. Verify you haven’t already used the code or applied it to your address.
4. Ensure your order meets any minimum purchase or product requirements.
5. Re-enter the code carefully, avoiding typos or extra spaces.

If you still have trouble, try a different code from a verified source or contact ByHeart customer support for help.

Pro tip: Always review the promo code’s terms and conditions before applying, and keep an eye on ByHeart’s official site for the latest eligible codes.

No, ByHeart does not allow stacking of promo codes. Only one promo code can be used per order, and you cannot combine a discount code with a referral code or any other offer. The checkout system will only accept the first valid code entered and will ignore or reject any additional codes.

This policy is consistent across all ByHeart promotions, including sitewide sales, referral bonuses, and exclusive offers. Attempting to stack codes will result in an error or only the highest-value code being applied.

Pro tip: Compare available codes before checkout and use the one that gives you the greatest savings for your order—especially during special promotions or for first-time purchases.
