to buy at costco can I enter without a supermarket card? or do I need a registration number? I am a tourist and I want to visit the place, how do I get the card ????

Only with membership. There are also other similar stores, BJs, that do give passes for a day. Would be an option

Hello Tatiana and how did you manage it? And where do you return it? Do they give it to you at the moment?

They gave me the membership service that cost $120, I used it for two days, and I returned it because I was going to leave the USA, and at that moment they refunded the money to my card

Good morning without cards you can not enter and less buy I recommend if you have a family member or friend who has the membership, take you because you cannot buy alone with someone else's membership and the cheapest I think is $ 45 per year 👍

You must have a Membership.

You have to have a card

You need to be a member.

Only with menbresia

You need to have a store card and you get it right there.
