Booking DCL through Expedia.. anyone done it?

[LAX]

Yes, the first thing they ask for is your Costco membership number. You might be able to book under someone you know that has a Costco membership. But keep in mind after completion of the trip the Costco cash card will be mailed with their name and address. But then again, how would you spend the cash card without the membership ID unless you went shopping with the person who has the membership.

I know it may not be relevant to this thread, but you can purchase merchandise at Costcos using a Costco cash card without being a member (don't even need to be with a member at all). I have done this countless times before I became a member myself.
