Q: My Keystone promo code isn't working — what should I do?

A: Try these troubleshooting steps in order: (1) Check the code is spelled correctly — some codes are case-sensitive. (2) Verify your cart meets the minimum purchase requirement. (3) Confirm the coupon hasn't expired yet. (4) Make sure the code applies to items in your cart — some exclude sale items or specific brands. (5) Try a different code from our verified list. If none work, please report the issue via our Contact Us page so we can re-verify it.

Q: Can I stack multiple Keystone coupons on one order?

However, you can often combine a single coupon code with automatic site-wide discounts and free shipping promotions. Always read the coupon's terms — some explicitly state "cannot be combined with other offers".
