I had one. I've been living on my own for 7 yrs, and we've been living together for almost 3 yrs, so I have alot of things but not nice new things - and like it was mentioned above, they wont last another 15 yrs. At first I didnt really want one because I felt like everyone was already spending alot of $ to go to the DW. But, my future sister in law convinced me to register because there would be several people who wouldnt be going to the wedding and would still like to buy a gift, so I did. My future mother in law ended up throwing me a surprise shower, and it was so lovely and touching. Pretty much everything I had registered for was purchased. I registered at 2 different places - Bed Bath and Beyond for everyday stuff, and Crate & Barrel for my entertainment pieces, and I registered for things in alot of different price points. I know this sounds so cliche, but I registered for fine china and was gifted the entire set of service for 12! Although I have no plans of hosting Xmas or Thxgiving dinners anytime soon, I prob will be in the next few yrs so it's nice that I will have nice china already.
You can always just register for the things you absolutely need and in different price points, or do the honeyfund - that'll be really nice to do things while you're on your honeymoon.
If someone volunteers to throw a shower for you, go ahead and let them do it. This is one of the few times people will be making a big fuss over you, and they're all happy to share in your special day, so enjoy it!
