Okay, so I'm not sure if this is where this belongs, but here goes. For my shower, I received two of the same item. The registry wasn't updated fast enough and two different people got me the same thing. I can return it, but I've told my FI that we can't use things until after the wedding. I have a gift receipt and can exchange it for something we can really use on the honeymoon. Since we leave for our honeymoon the day after our wedding, is it okay to return the item now and get the other thing, or should I wait until after the wedding to even exchange it? FI says doesn't exchanging it count as "using it?" Thank you in advance for any help!
