I found this one today. I just couldn’t let you go a whole Christmas shopping week without having it.
Amazon shopping tips from Pro Bargin Hunter (hat tip Lifehacker) shows you (among other things) how to edit the URL at Amazon to only look for things that are on sale and/or available for free shipping. Too scared to edit URLs? Maybe just too lazy? Check the update at the bottom where someone made a pull down menu to do all the work for you.
