Returning or reselling baby shower gifts

Ceejay • Currently pregnant with baby #1

Hi ladies! We all set up registries for our babies and our postpartum needs (some people are even saying registries are just for baby things not things mamas need). There’s a women who is getting a lot of backlash for returning/ reselling gifts that were purchased off the registry to purchase the items she has on the registry. Is she wrong for doing this?
