Costco: Can you return, when credit card holder not present

Here’s the deal. Some products were purchased with my wife’s credit card.
Work and scheduling obligations are keeping her from returning to the store. The end of thirty days is fast approaching.
Can I use her credit card
to accept the refund?
Can it go into “store credit” until the wife can come to the store transfer the money? I think Costco doesn’t give cash returns on credit purchases.
