FI is Jewish, and while I'm half Jewish, I've always considered myself to be more Christian, but that doesn't mean I don't enjoy adding more holidays to my repertoire. 
There are some really cute Passover seder plates available at the places we've registered, and I would like to add one to our registry, but FI says that we should just let people guy them from their synagogues. This seems odd to me since then A) we have no say in how it looks, and we'd be unable to return it easily, 

 is that something people do?
As I said, I've never been affiliated with a synagogue (or even a church for that matter), so I'm actually clueless. But FI has a habit of getting these sorts of things, uh, wrong. (He thought at showers we give our guests gifts.)
Anyone able to provide some clarity?
