FWIW - amazon.com has 'Wish Lists' that do the same thing. At first, you could only tag items from Amazon itself; but now you can add items from anywere on the 'net.
Over the summer, I filled my list with a bunch of items (with a variety of prices) and when someone asked what I wanted for birthday or Xmas, my loving wife would steer them to my list.
I got a bunch of stuff that I really wanted.
Don't get me wrong. The holidays are still a bunch of crock that I would prefer to avoid, but at least people were able to get me stuff I wanted* (and not another glove & scarf combo pack). Likewise I was able to get stuff for my kids that I knew they wanted.
*I'm not greedy or cheap; I just hate the waste of getting or giving the wrong thing.
