My son bought me a bottle of Cool Water cologne for my birthday! Can I exchange it or get a refund because I don’t have a receipt?

Yes

Yes, but at the lowest price they have had it for sale. You may not get what he paid for it.

Yes, but I wouldnt because your son bought it for you

I agree. No receipt = exchange only.

I believe you can exchange it for something of equal value.

You can exchange. But no money back , but weather or not I would keep it because my son brought it I'm just saying

Exchange or store credit no refund without receipt.
