We have partnered with both UPS and the USPS to bring you the best delivery possible. Most packages under 3lbs will be shipped via USPS while those larger and heavier packages will go UPS ground. UPS second and third day delivery is available for additional charge by calling customer service at 1-888-442-6161. BIO INNOVATIONS reserves the right to select the best shipping method for the delivery address. BIO INNOVATIONS does not ship outside of the United States.
