Maria Killam Promo Codes & Coupons June 2026

Maria Killam promo codes are generally not case sensitive — you can enter them in uppercase, lowercase, or mixed case and they should apply correctly at checkout.

That said, errors can still occur when copying codes with extra spaces or when a mobile keyboard auto-capitalizes. To avoid issues, follow these steps:

1. Copy the code exactly as shown (e.g., KILLAM10).
2. At checkout, paste it into the "Promo Code" box below your cart items.
3. Click "Apply Coupon" — the discount should appear instantly if you meet any minimum order requirement.

Keep in mind that codes do expire and sitewide codes may exclude items already on sale.

Pro tip: If a code isn't working, try clearing your browser cache or switching to a desktop browser, then paste the code rather than typing it manually.

No, Maria Killam allows only one promo code per order. This is standard practice and matches the single promo code field available at checkout.

If you try to enter more than one code, the second entry will typically override the first. To make the most of your savings:

1. Add your items to the cart, making sure you meet any minimum order threshold.
2. Compare available codes and identify the one offering the highest discount percentage.
3. Enter that code in the promo code field and click "Apply."

Note that during sitewide sales events like Black Friday, no promo code may be needed at all — discounts are applied automatically.

Pro tip: If you haven't signed up for the Maria Killam email list yet, do so before checkout. New subscribers may receive an exclusive single-use discount code that could outperform publicly available codes.

Yes, many Maria Killam promo codes apply to online courses, color wheels, ebooks, and other digital products available on mariakillam.com.

Sitewide codes are generally valid across her digital catalog, including Killam Colour System downloads and educational resources, as long as you meet any minimum order requirement. Restrictions typically include exclusions on already-discounted or sale items.

To apply a code to a digital purchase:

1. Add your courses or digital products to your cart at mariakillam.com.
2. Proceed to checkout and paste your code into the "Coupon code" field.
3. Click "Apply" and confirm the discount is reflected before completing payment.

Pro tip: If you're making your first purchase, sign up for the Maria Killam email newsletter before checking out — new subscribers may receive a welcome discount that applies to digital products.

If your Maria Killam promo code isn't applying during PayPal checkout, the most likely cause is that the code was entered after initiating the PayPal redirect rather than before. PayPal redirects can sometimes reset or refresh your cart session, causing a previously entered code to drop off.

To avoid this issue, follow these steps:

1. Add your items to the cart and confirm you meet any minimum order requirement.
2. Enter your promo code in the "Promo Code" field and click "Apply" — verify that the discount is showing in your order total.
3. Only after confirming the discount is applied should you select PayPal as your payment method and complete the transaction.

Pro tip: For the smoothest experience, apply your promo code on a desktop browser rather than mobile, and take a screenshot of your discounted cart total before proceeding to PayPal in case you need to reference it later.
