This option is for our customers who would prefer an overnight delivery of their package. This option is expensive because it's Next Day Air and that service is priced according to weight. This option provides delivery within 24 hours of shipment.
We cannot offer this service to our customers in Hawaii and Alaska, unfortunately.
USPS is always complimentary, but delivery/transit times cannot be guaranteed. If you would prefer guaranteed 1-2 days this is the best option for transit speed right now.
