Too late for me - my husband finally gave up on waiting for it and made his order on Thursday to be sure it'd be here for Christmas. And since the wishlist here doesn't remove items that have been bought for you, I won't know till Christmas morning what's safe for me to buy without duplicating.
Oh, I use the favorites list for that, since my wishlist has to be just a wishlist since people who aren't me buy from it (well, not "people", but a person). On a product page, next to the Wish List button is "Add to Favorites" - I use that for items I might want again, or just items that I want to remember exist.
Early Christmas afternoon, every year, I go through my actual wishlist and remove all the goodies I got to open earlier in the morning. (Also after every order I make for myself!)
