Unfortunately, our system provider who looks after all the back-end systems of Starbucks AP (Asia Pacific) completed a white-washing task, this was to improve security for customer's accounts, and when this occurred it limited the ability of overseas IP addresses from purchasing gift cards and other items from our website, as it was not registering as a local network.
Due to this, our system will not allow overseas networks to purchase our gift cards, our sincere apologies for the inconvenience and news this presents.
