Personally, I use Amazon's wish list as a "buying buffer"; I store things in there that I want to buy (for myself) just not Buy Right Now.
I just saw this book I'm interested in but I don't want to buy it right now. I can't find any way to save it (like in a wish list ;-) so I'm going to have to rely on my memory, IOW, I'll forget about it. :-)
