Currently, UPS Ground services are all that are offered for shipping your goods to the Lower 48. We don't ship Internationally. All packages through UPS are weight based, so the prices that you are charged are the prices that UPS calculate you for shipment.
If you live in Alaska, Hawaii, Puerto Rico and any of the American Island chains, including Guam, we do offer a Packaging Service called Aloha Forwarding. They can be found at http://www.alohaforwarding.com. They send all their customers packages using the US Postal Service to any US zip code. There is no cost to join this service, just the cost of the shipment itself. Contact them to set up an account, then use the address given when you order from us. If you have mulitple shipments from different Sellers, they will try and put as many of your shipments into one box to save you money.
