Last year I did a ton of shopping on Amazon. I signed up for a free trial of Prime and was able to get free 2 day shipping without having to add additional items to get my total to $25 for free shipping. It was great to be able to ship the packages right to my inlaws house (where we were for Christmas) rather than having to pack and bring them with us.
Each day they have different great deals and often the prices can change even throughout the day. A good way to find hot items is to look on the "Movers and Shakers" page.
Here's something currently found there--marked down to $29.99 from $99.99
