My sister-in-law's in-law's very sweetly got us a few gifts for the baby. In the bag was a bath set that includes some scented products I'd prefer not to use, as well as non-cloth-friendly diaper cream. I have no idea where she purchased it. Does anyone know if I set up a registry somewhere (Target, BRU?), add this item to it, and then mark it as purchased, will I be able to exchange it for something else? Or will that not work because they will not have record of the purchase?

If I can't exchange, I'll just donate it somewhere, but I was curious how this all works.
