Someone bought a stroller for us that wasn't the one on our registry. I'm very grateful for their generosity...and it's new and they asked first but we said no because we did a lot of research on it. We purposefully picked one that seemed safe as well as inexpensive. They got a different one anyway because they didn't want to order online and they were currently out of stock in store. It's a travel system that includes the car seat, which is really important to me to be safe. The reviews aren't great on the one they bought and say the stroller can collapse on a baby. Do we risk offending the gifter by returning it for the one we registered for? I think they will notice because the one they bought is also bright green and the one we're requesting is grey. Do we keep the original request on the registry? Need advice!!!
