Why Isn't My TESmart Coupon Working?

If a TESmart code won't apply at checkout, a few common causes explain most cases:

• One-time or new-customer only: some codes are restricted to first orders and won't apply to a returning customer's cart.
• Excluded items: sale or clearance items are often excluded from storewide percentage codes.
• Case sensitivity or extra spaces: copy the code directly and paste it without a leading or trailing space.
• Expired or regional offer: some codes are time-limited or valid only for a specific country's store.
• Minimum spend not met: check whether the offer requires a minimum order value before it activates.

If a code still won't work after checking these, the offer has likely expired since our last verification — let us know so we can review it.

Q: How do I use a TESmart coupon code? A: Click "Show Coupon Code" on the offer, copy the code, shop on the brand's site, then paste it into the promo or discount field at checkout before you pay. Offers marked "Deal" apply automatically once you click through.
