I didn't register when we got married. I can see the pro's for doing so, but I like to be surprised!! We had a big wedding, and got some lovely presents. Amazingly, we only doubled up on one thing that mattered - we got two crockpots. Thankfully, I was able to return the second one.
Some people did ask me what we wanted, so I managed to mention some of the things that we really needed.
And we got given money by a number of people. Contrary to what appears to be popular opinion, this was VERY much appreciated. We were just starting out, and there are some things that you just don't get as wedding presents. Coat hangers, pegs, a washing basket... to name a few! And I still look at the presents I bought with the money, and remember the person who gave it to us (i.e. 'Auntie Carolyn's breadmaker' etc).
