What I always thought was "normal" was to give everyday items for the shower, and formal items for the wedding. That is what my mom taught me, anyway. Well, that all changed when I moved east. For all of our friends here, and ourselves when we got married, people got pretty much EVERYTHING off their registry for their showers...showers here are huge, too. Mine had only 35 people and is talked about as being small. I come from an area where 15 people is more normal! Here I've been to showers that had 100+ people at them.
Weddings are usually cash/checks. I got all of my china, crystal, most of my silver, as well as all of my everyday stuff...towles, flatware, pots/pans, etc. for my shower. For the wedding 90% gave cash...almost all in the 3 figures.
I have NEVER heard people announce how much they received...I've never seen anyone open anything at a wedding. As for gifts, they are mostly sent ahead of time so no hauling from the reception.
