Once Upon A Tee Promo Codes & Coupons September 2025

If your Once Upon A Tee promo code isn’t working, even though it appears valid, it’s likely due to specific restrictions or requirements not being met. You may need to be logged in, use the code on eligible items, or ensure you haven’t already used a single-use code.

Common reasons for codes not working include:

• The code is single-use and has already been redeemed (codes from rewards and referrals are typically one-time use).
• The code is not valid with other promotions or sale items (Once Upon A Tee does not allow stacking of discounts).
• You may need to meet a minimum purchase amount or buy from a specific collection.
• Expired codes or codes restricted to new customers only.

To troubleshoot:

1. Log in to your Once Upon A Tee account before applying the code.
2. Double-check the code’s terms (single-use, item/category restrictions, minimum spend).
3. Ensure your cart doesn’t include other discounts or promotions.
4. Enter the code in the promo code box at checkout and click “Apply.”

Pro tip: Always check the code’s details and expiration, and try applying it before finalizing your cart to avoid missing out on savings.

This error means you can’t combine your promo code with any other ongoing sale, discount, or promotion on Once Upon A Tee. Stacking multiple codes or rewards in a single order is not allowed.

Once Upon A Tee’s checkout system will only let you use one promo code per order, and it will block any attempt to combine codes or use a code on already discounted items. This is a common restriction for their site-wide and exclusive codes.

To resolve this:

1. Remove any other discounts or sale items from your cart.
2. Apply only one promo code at checkout.
3. If you have multiple codes, choose the one that gives you the best value.

Pro tip: Save unused codes for future orders—Once Upon A Tee’s single-use codes can’t be reissued if you share or lose them.

• Minimum order value required to activate the code.
• Exclusions on limited edition, collaboration, or already discounted items.
• Single-use codes tied to your account or email (especially for rewards or referrals).
• New customer-only codes, such as newsletter sign-up discounts.

Always review the terms provided with each code, as restrictions can vary by promotion.

Pro tip: Check the fine print or promo details before shopping to avoid surprises at checkout and maximize your savings.

Once Upon A Tee does not apply promo codes retroactively after an order is placed. Their policy states that coupons must be applied during checkout and are only valid at the time of purchase.

If you forget to use a code or encounter an error, customer service typically cannot adjust your order after payment is complete. This is a standard policy to prevent misuse and ensure fairness.

To avoid this:

1. Double-check your code and cart before submitting your order.
2. If you experience a technical issue, contact customer support immediately before completing your purchase.

Pro tip: Always enter your promo code before finalizing payment—Once Upon A Tee cannot add discounts after the fact.
