I loooove Christmas. I also happen to love planning and lists and such. The Organizing Junkie wrote a great post that included a review on an awesome app that I love! Christmas Gift List is a super easy way to keep track of gifts you need to buy, which ones you've already bought and what's already wrapped and you've forgotten about *raises hand*
You can even password it so it's safe from prying eyes ;)
This is now my 2nd year using this app. I even used it for birthday shopping!
