Crest Promo Codes & Coupons February 2026

Your promo code likely isn't working because it's expired, doesn't meet the minimum purchase requirement, or you're trying to combine it with another offer. Crest explicitly states that codes cannot be combined with any other offer, and many codes have specific eligibility requirements like minimum order amounts.

Common reasons codes fail include expired dates—always verify the code's validity before checkout. If you're shopping on Crest's official website, check that your purchase meets the minimum threshold. For example, the CND36 code requires a $250+ purchase, while other codes may have different minimums. Additionally, some codes are retailer-specific and only work through authorized resellers like Walmart or iHerb, not directly on crest.com.

If you're using a code from a coupon aggregator site, verify it was last successfully used recently. Some codes tracked on sites like SimplyCodes show "last used 1+ months ago," which may indicate they're no longer active. Also check whether you're applying a code meant for a different Crest product line—for instance, professional whitening codes like CWSFLASH are restricted to Professional and Professional Elite accounts only.

Pro tip: Before entering a code at checkout, cross-reference it on multiple coupon sites to confirm it's currently active and check the "last verified" or "last used" dates to ensure it's still working.

No, Crest does not allow combining multiple promo codes on a single order. Their coupon policy explicitly states that codes "cannot be combined with any other offer," whether you're shopping on their official website or at authorized retailers.

This restriction applies across all Crest promotions. If you have multiple codes available, you'll need to choose the one that provides the best discount for your specific purchase. For example, if you're spending $1,500, the SAVE100NOW code ($100 off $1,000+) would be better than CND36 ($25 off $250+), but you can't stack them.

The only exception to this rule involves automatic discounts that aren't coupon codes. For instance, Target RedCard holders receive an automatic 5% discount on Crest products, and this discount can potentially be applied alongside a promo code since it's not technically a "coupon code"—though you should verify this with Target before checkout.

Pro tip: Calculate which single code saves you the most money before checkout, and if you're a Target RedCard holder, use that for automatic savings while applying your best promo code separately.

Most Crest promo codes work on both subscription orders and one-time purchases, but this varies by code and should be verified before checkout.

Some codes may have restrictions that implicitly exclude subscriptions (for example, if a code is limited to "merchandise only," it might not apply to recurring charges). Additionally, single-use codes tracked on coupon sites may have specific eligibility requirements that could exclude subscriptions.

Your best approach is to add items to your cart and attempt to apply the code during checkout. If it fails, you'll receive an error message indicating why. If you're unsure, contact Crest's customer service before completing your order to confirm whether your specific code works with subscription purchases.

Pro tip: Test your promo code in the cart before committing to a subscription—this way you can see if it applies and switch codes if needed without being locked into a recurring charge.

An "invalid code" error typically means the code has expired, doesn't meet your purchase requirements, or isn't compatible with your cart contents. Here's what to do:

1. Verify the code's expiration date and check that your order total meets the minimum purchase threshold—many Crest codes require $250, $1,000, or $2,000+ purchases.
2. Confirm you're entering the code correctly. Promo codes are case-sensitive and sensitive to extra spaces, so copy and paste the code directly from your source rather than typing it manually.
3. If shopping at an authorized reseller like Walmart or iHerb, make sure you're using the reseller-specific code rather than a code meant for crest.com.
4. Check whether the code is restricted to specific products or account types. For example, professional whitening codes only work for Professional and Professional Elite accounts.
5. If you've already used a single-use code on your account, it won't work again—some codes are limited to one redemption per customer.

If the error persists after verifying all these factors, the code may simply be expired or no longer active. Try a different code from a reputable coupon aggregator site like SimplyCodes, which track "last verified" dates to confirm codes are currently working.

Pro tip: If you encounter an "invalid code" error, clear your browser cache and try again—sometimes cached checkout data causes false errors. If it still fails, contact Crest's customer service with the specific error message and code you used.

Crest may occasionally offer discount codes, but currently, there are none available. However, customers can still save money by taking advantage of other promotional offers or sales available on the website, or by using credit card points to make purchases.
