I got really excited about this when I found out about it, but have barely used it since. Maybe it's because the only person who buys me stuff from my Wish List is my Mom.
I wish there was some magic to this, but it's just a static entry in the wish list that doesn't reflect any changes that may occur to the offering after adding it.<p>I didn't think much of that until I noticed myself automatically skipping past those entries visually while examining the contents of my wish list. I don't trust that information, so it's ignored.
