Secure Shopping

We know how important security is, so you can place your order with confidence. All of the information you share with us online is encrypted by what is called a Secured Socket Layer, or SSL. You can see this for yourself! You know that a web site has SSL when the URL begins with https:// rather than just http://. Also you will find an icon of a locked padlock. It is usually found near the URL bar, but may be in a different location depending upon your browser.

With state of the art 256-bit SSL technology, your important data is encrypted before it even leaves your computer. Your credit card transaction is handled directly with our processing service; no employee of Theta Chi Official Store ever has access to credit card numbers entered online.

We’re also easy to find! We are headquartered in Indianapolis, Indiana. You can call and speak with one of our friendly staff members and we’ll be happy to help in any way we can.

Satisfaction Guarantee

We want you to love what you ordered from us. That's why we kept your best interests in mind as a customer when we created our policies.

Hassle Free Returns and Exchanges

You can order with confidence knowing that you can return and exchange most items that you've ordered! Please read our returns and exchanges policy for more information.

Address Corrections

If you need to update the shipping address in your order and it hasn’t shipped, we can still make changes for you! Please email us at questions@shopthetachi.com with your order information and we'll work with you to get this updated.

Order Cancellations

If your order hasn’t shipped and you'd like to cancel it for any reason, we're able to cancel this for you. Please email us at questions@shopthetachi.com with your order information to request an order cancellation. If your order has already been shipped, please see our returns and exchanges page for information on returning your order!

Damaged or Incorrect Items

If your item(s) come damaged or incorrect, we want to make it right. Please email us with your name, order number, and a picture to verify, and we'll issue you a return label. We want you to love what you ordered!
