Hi Calm,
Prior to my wedding, I probably would have bristled at the impersonal nature of cash as a wedding gift, but after my wedding, the cash was appreciated so much and totally changed my mind.
We were able to apportion some to the little things we needed as a couple with a little rapscallion, and we were also able to use some of it to make our honeymoon so much more memorable. Instead of it being meticulously planned out financially (like it was initially), we were able to pepper in a few additional fun things, like an impromptu night at the Grand America in Salt Lake, and a fancy dinner (I had capers for the very first time). I have lifetime memories that I otherwise never could have dreamed of because of those little cash wedding gifts.
There are a few physical gifts, that even in separation/divorce are still deeply treasured and meaningful, but the memories (and reduced stress with getting some additional furniture items, and appliances) from those cash gifts are absolutely invaluable to me.
