Kossma Promo Codes & Coupons February 2026

Your Kossma promo code is likely invalid for your cart because it's not compatible with the specific items you're purchasing. Many Kossma codes target select products only (for example, some codes work only on regular-priced items but not kits or supplements).

If you're seeing an error message like "Promo code is not valid for items in your cart," here's how to fix it:

1. Check the specific terms of your promo code to see if there are item restrictions
2. Remove any incompatible items from your cart
3. Paste the code in the promo box at checkout and hit apply
4. If it still doesn't work, try alternative codes like BF2024 (20% sitewide) or other current promotions

Pro tip: Test promo codes on single-item carts first to quickly identify which products are excluded from specific promotions.

You cannot use an expired Kossma code - they automatically fail with an "Code expired" message at checkout. For Black Friday deals, you'll need to find current codes when they become available.

Here's how to find current Kossma promo codes:

1. Visit coupon sites like SimplyCodes for the latest verified codes
2. Copy and paste the code at Kossma checkout
3. For Black Friday specifically, check Kossma's emails and social media in November, as these seasonal codes typically launch mid-November
4. Note that Black Friday deals rarely extend past December

Pro tip: Subscribe to Kossma's email list now to receive Black Friday codes 1-2 weeks before they're widely available.

The exact error message is "Promo code is not valid for the items you have selected," which appears when you try to use category-specific codes on products they don't apply to. For example, using a supplements-only code on skincare products.

To fix this issue:

1. Note what products your code is intended for (some codes only work on specific categories)
2. Clear your cart and add only eligible items
3. Re-enter the promo code before payment
4. If available, try using a sitewide code instead

Pro tip: Take Kossma's wellness quiz for an instant 15% off your first order, which works on most products including kits—this can bypass many code restrictions.

No, Kossma doesn't allow stacking affiliate codes with sitewide promotions. Only one discount code can be applied per order. When you try to add a second code, you'll receive an error message stating "Only one promo code per order."

Affiliate discounts (typically 10% off) automatically apply when you click through an affiliate link. If you then try to enter a sitewide promo code, it will either replace the affiliate discount or be rejected.

Pro tip: Compare the value of the affiliate code (usually 10% off) against any available sitewide promotions (which might be 15-20% off during sales), and use whichever gives you the better discount.

Yes, Kossma promo codes typically cannot be combined with sale items. If you try, you'll likely see an error message stating "Not valid on sale or discounted products." This is especially common with kits that are already discounted from their individual component prices.

Here's how to work around this limitation:

1. Check item tags before adding to cart to identify which are on sale
2. Use promo codes only on full-price items
3. Consider whether the sale price or the full price with a promo code gives you a better deal

Pro tip: If you're shopping during a sale, try adding items to your cart separately—full-price items with a promo code in one order, and sale items in another—to maximize your savings.
