Even though we don’t live anywhere near a Costco we just got a membership as part of refinancing our home. We have our member number so I checked alamo and got a $180 savings on our rental for this month’s trip! My question is this: the member number comes up as my husband’s name only although he could put me as the renter (he won’t be with us). Is that going to be a problem? Can I print out the member number as proof of membership if they ask? Our Sam’s membership includes both of us-does Costco work that way? He does travel for work and is in a town today that has a Costco. Should he try to get both of us cards?
