Can I exchange Pampers for a different size without being a member they were a gift.

Maybe!!!

I don't think so

yes

Not sure

Probably not.

I'm not sure about that. I would call the store. Typically they ask for a membership card in the return center.

I am not sure , but you will be able to get a pass just for one day.

I don't know

If you have the name of the person who gave them to you, the information desk should be able to pull up their past receipts. I have always found the employees there to be super helpful and would say it's worth a shot.

No

I'm not sure but Costco customer service is excellent so I would go in and ask!
