Greetings Sam,
Recently we stopped offering the USPS's Express International shipping option. This option was more affordable at around $40 nearly anywhere on the globe, but we've found that service to be less than reliable, leaving us open to credit card chargebacks. We now only offer UPS shipping service.
We only offer the UPS Worldwide Saver and UPS Worldwide Express options. We don't offer UPS international ground as delivery can take several weeks. (We've offered slow service in the past, but typically customers end up filing chargebacks when the parcel takes longer than two weeks to arrive, so we only offer the fastest shipping options).
International customers may have difficulty getting their credit card to work with our credit card processing gateway, Authorize.net. You may also try using PayPal payment option with greater chance of success.
