Case-Mate Promo Codes & Coupons September 2025

A Case-Mate promo code may show as "code not valid" or "expired" because codes can expire quickly, be single-use, or have specific requirements.

Reasons for this error include:

• The code has already expired or reached its usage limit.
• The code is case-sensitive or requires exact entry.
• The promo code may be single-use or restricted to specific accounts.
• Your cart may not meet the code’s requirements (e.g., minimum spend, eligible items, or first-time buyer status).

To troubleshoot:

1. Double-check the code for typos and ensure you’re entering it exactly as shown.
2. Review the code’s terms for expiration dates, usage limits, or item/category restrictions.
3. Try another verified code from a reputable source.
4. If you believe the code should work, contact Case-Mate customer support for clarification.

Pro tip: Always use codes from sources that track real-time success rates and avoid codes labeled as “expired” or “single-use” unless you’re sure they’re still valid.

Case-Mate typically allows only one promo code per order, and most codes cannot be combined with other offers, including free shipping promotions.

When you enter a promo code at checkout, the system will usually apply only the most recent code and remove any previously entered ones. This means you must choose the best available discount for your order. Free shipping offers may be automatically applied if your order meets the minimum threshold, but using a promo code for a discount may override or exclude other offers.

If you try to enter multiple codes, you’ll likely see an error or the previous code will be replaced. Always review the order summary to confirm which discount is active.

Pro tip: Calculate which promo code or offer gives you the highest total savings, factoring in shipping costs, before finalizing your order.

Certain Case-Mate promo codes exclude sale items, limited-edition products, or specific categories like bundles and accessories. Codes often apply only to full-priced merchandise and may require a minimum purchase amount.

Common exclusions include:

• Sale or clearance items
• Gift cards or select collaborations
• Items already part of a sitewide promotion

To check if your cart qualifies:

1. Review the promo code’s terms and conditions.
2. At checkout, enter the code in the “Discount code or gift card” field—if your cart doesn’t qualify, you’ll see an error message or no discount applied.
3. Remove excluded items or adjust your cart to meet any minimum spend requirements.

Pro tip: Always check the fine print of each promo code and test it at checkout before finalizing your order—if it doesn’t apply, try removing sale items or adjusting your cart to see if the code works.
