I think it kind of depends on the couple, too. I was only 21 when I got married, so although we did already have plates and frying pans and sheets, they were all either JUNK or hand me downs. I LOVED getting shiny new things that I would not have otherwise been able to afford.
My ex husband was at my house the other day installing a ceiling fan for me and noted a bright yellow colander in the sink. “That looks familiar, did we get that when we got married?” This coming from the dude who does not pay attention to anything. Gifts matter to people.
My best friend had put a fire extinguisher on her registry, and I totally bought it for her shower gift. She was stoked! So if it’s on there, it’s fair game.
