Sandal Me

I am really warming to this ingenious registry idea of mine. I'm just so clever. One of the best aspects of the "buy me things" registry is that you don't have to share it with anyone. No one is going to argue with you over a single choice you make because it's, say, redundant. Or, how do you say it? Unnecessary. Or, what's that word again? Frivolous. Or even because you don't have room for the shoes you already have. Throw these $40 galadiators on the registry, baby.

Where do I get one of those registry bar code scanners, so that I can keep it in my purse and whip it out at the sight of a must-have item, regardless of the store I'm in? Surely there's already an iPhone app.
