At this time, we currently only offer USPS shipping services. US shipping is free for orders over $15, and we ship all free packages via USPS First Class Mail or USPS Priority Mail (depending on weight). All free shipping orders over 8 samples are shipped USPS Priority Mail. If the expedited upgrade is chosen, it will always be shipped USPS Priority Express.
We will offer UPS and FedEx shipping services in the near future. For now, we can't offer any other services, even by request.
