Because of component shortage, Oculus announced they plan to shoulder shipping fees for pre-orders made until April 2nd, including international orders. They expect to update shipping information by April 12th. The move made by Oculus will save a lot of international customers some money. Reddit user SvenViking says it'll save them over $132 AUD (roughly $131 CAD) from expected cost. Oculus CEO Brendan Iribe confirmed the savings and apologized for not letting customers know earlier about the delay.
