Unfortunately, we cannot do that because merchandise needs extra protection, and USPS does not provide a tracking number for this type of service.- The shipping service we offer is First-Class Package Service, which is a domestic mail service offered by USPS. It is designed for mailing lightweight packages that weigh up to 15.99 ounces and offers delivery in 1-5 business days. It includes a tracking number, allowing customers to track their packages. USPS prices start at $4.75, but we don't have any control over shipping prices.
