Yes, I've heard of that. I do like that better than just asking for cash. Though, as I already said, Italians give money at weddings. It's cultural - the "boosta bag" ! And, again, it is customary to "cover your plate". But that is just a guesstimate, hopefully no one would actually tell guests what they are paying per person. I am sure that at one time there were no registries. But, I am married 31 years and there were registries when I got married. They just were not on store computers or on line (obviously ). So, you almost had to go to the store they were registered at. Not just Macy's, but the Macy's they went to. Now all of that is shared. And there are web sites that have all of the couples choices at all of the registry stores combined into one list.
