USPS Flat-Rate Shipping is available to all contiguous U.S. addresses.

While shipping is available, as this is a pre-order sale, we cannot guarantee shirts will ship in time to arrive for Pi Day.

Once your order is packed and a shipping label is made, you will automatically receive an email with a tracking number

We offer USPS Flat-Rate Shipping (3-5 business days). The 3-5 business day shipping estimate is how long it will take for the item to arrive to you once your order gets put in the mail, not how long it will take to get from the time you ordered. We will always try our best to mail orders as quickly as possible.

Live outside the contiguous U.S. (Alaska, Hawai'i, Canada, Mexico, etc.) and want to have a shirt shipped to you? Send an email to hello@sisterpie.com to place an order.
