If you are Costco member of some countries, you can use your original membership to register the Costco TW online account and purchase/deliver to your hotel. (
Australia, France, Iceland, Japan, Mexico, South Korea, Spain or the UK)

Costco Taiwan requires national ID or ARC for online membership though, and there’s no option to register an account without membership like costco.com.
