Kits ship near the 15th of each month via United States Postal Service (USPS) or UPS, depending on your location. Kits shipped in the United States are shipped priority mail which usually takes 1-3 business days. International shipments sent via USPS can take 1-3 weeks. Shipping to the United States and shipping internationally may take a little longer during times of heavy mail traffic (i.e. holidays).
