Do DTK Nail Supply promo codes work on sale or clearance items?

DTK Nail Supply promo codes typically do not work on sale or clearance items. The system recognizes these items as already discounted and will usually trigger errors like "Invalid code for these items" when you attempt to apply additional discounts. This limitation is especially noticeable during big sales events. For example, clearance gels marked down 50% won't accept promotional codes like SAVE5NOW. DTK's checkout system prioritizes the base sale prices, which is a common practice in nail supply stores to prevent excessive discounting on inventory. If you want to use a promo code while also purchasing sale items, try these steps: 1. Remove sale items from your cart 2. Apply the promo code to full-price items first 3. Add the sale items back to your cart 4. Re-enter the code if the subtotal changes Pro tip: Look for codes specifically labeled as "sitewide" before adding clearance items to your cart, and test the code in your cart preview to avoid checkout issues.

Can I combine multiple promo codes during DTK Nail Supply checkout?

No, DTK Nail Supply does not allow combining multiple promo codes during checkout. You can only use one promotional code per transaction. If you try to enter multiple codes, the system will display an error message like "Only one code allowed." This is standard practice for nail supply retailers to maintain profit margins. When deciding which code to use, follow these steps: 1. Compare available codes to find the highest value (e.g., choose 20% NLXSAVE5 over 5% SAVE05) 2. Enter only that code in the "Promo Code" box at checkout 3. Click Apply to activate the discount Note that loyalty points redemptions (such as 1000 points = 10% off) also cannot be combined with promo codes in the same transaction. Pro tip: To maximize savings, use your best promo code on one order and save your loyalty points for a separate purchase.

How do I resolve 'invalid code' errors when shopping at DTK Nail Supply?

When you encounter "Invalid code" or "Wrong discount code applied!" errors at DTK Nail Supply checkout, try these troubleshooting steps: 1. Remove any sale or clearance items from your cart 2. Verify that the promo code hasn't expired 3. Copy and paste the code exactly as shown (check for spaces or capitalization) 4. Ensure you're using the code on eligible items only 5. Try clearing your browser cache or using incognito mode 6. Check if your shipping address affects code eligibility Some codes like DNDLACEXTRA15 specifically won't work on clearance items (such as DND gels). DTK automatically applies some deals but rejects codes that don't match your cart contents. If you continue having issues, try an alternate code like SNSSAVE10 or consider creating an account to earn loyalty points (new accounts receive 200 starter points). Pro tip: Test promo codes on small carts during non-sale periods for the highest success rate, as the system tends to have fewer restrictions outside of major promotional events.
