Where to return diapers??

Hi all, so my office threw me a baby shower last week and my family threw me one over the weekend. We are super grateful for everything and we got tons of diapers.

Does anyone know if there’s a store that accept diapers for an exchange? Not just in size but brand too? Or for a gift card so we can choose other diapers and wipes? I was told Walmart and Target but it looks like they change their policy and are asking for a receipt now. Nobody gave us receipts for the diapers.

Thank you ladies.
