I was gifted a Yankee Candle company wax warmer for christmas. On the way home from the party it broke. I was upset and my husband said go order another to replace it! (Awww thanks hun) today I got my package. Inside were 2 of the exact same warmer

I ordered 1. My shipping manifest even says 1. I was only charged for 1. I checked my online receipt and my bank statement. My question is what would you do? Contact the company and ask if I should return the 2nd or just keep it without saying anything. and if you say keep it should i gift it to someone or just have a 2nd warmer in my home? My sister says call them. I am torn. What should I do?
