theory — frequently asked

How can I get a Theory coupon code?

The easiest way to get a Theory coupon is by signing up for their newsletter, which offers 15% off your first full-price order.

Does Theory offer free shipping?

Yes, Theory provides free standard shipping on all US orders, with no minimum purchase required. Your order typically arrives within 5-7 business days. For faster delivery, they offer expedited shipping options for an additional fee.

Can I return sale items to Theory?

It depends on the discount. Most items can be returned within 30 days for a full refund or within 60 days for store credit. However, items discounted 41% or more, or marked as final sale, are not returnable. Always check the product page or your receipt for specific return eligibility.

How does Theory's student discount work?

Theory offers a 15% discount to current students and recent graduates (within 5 years) on select full-priced merchandise. To claim this discount, verify your status through StudentBeans on Theory's website. Once verified, you'll receive a unique coupon code to use on your purchase.

What is Theory's military discount policy?

Theory offers a special discount for military personnel, veterans, and their families. While the exact discount isn't publicly listed, you can verify your status through ID.me on Theory's website to access your savings. This discount applies to Theory's premium clothing and accessories.

How do I use a Theory promo code?

To use a Theory promo code, add items to your cart and proceed to checkout. Look for the "Promo Code" box on the checkout page, enter your code, and click "Apply". The discount will be applied to your order if it meets the code's terms and conditions.

What are Theory's Essential Duos and Trios?

Theory's Essential Duos and Trios are curated sets that offer built-in discounts when you purchase multiple items from the same style family. These bundles help you build a coordinated wardrobe while saving money, without needing a separate coupon code.

Does Theory have a loyalty program?

Theory doesn't mention a specific loyalty program on their website. However, they offer various ways to save, including email sign-up discounts, student and military discounts, and exclusive app offers. Check their website or contact customer service for the most up-to-date information on any loyalty initiatives.

How often does Theory have sales?

Theory doesn't publicly state a specific sale schedule. However, they regularly update their Sale section with discounts up to 70% off. For the best deals, sign up for their newsletter, follow their social media, and check their website frequently, especially during major shopping seasons like Black Friday and end-of-season transitions.

Can I use multiple Theory coupon codes on one order?

Generally, Theory allows only one promo code per order. However, some offers, like student or military discounts, may be combinable with other promotions. Always check the terms and conditions of each offer, or contact Theory's customer service for clarification on specific combinations.
