Advice on MIL gift

My MIL got us a travel system which I told my hubby when we registered - I did not want. I already bought a car seat. A very nice car seat - peg perego primo viaggio 4-35. She bought us a Graco Comfy Cruiser travel system for our baby shower gift. I'm flustered. What should I do? Hubby says we just just keep it and use it but I was so excited about using my car seat and getting an all-terrain stroller so that I could jog with baby and use it everywhere. The travel system is not even the color choices I'd like to have - it isn't gender neutral (bright pink and black). MIL is very involved in our lives so I don't want to upset her.
