What is the coolest thing you've purchased on Amazon (and why)?

I don’t know that I ever purchased anything that would be considered “cool” but I have purchased lots and lots of different things on Amazon, from books and toys to parts for lawnmowers, paint guns, and kitchen and bath items. I guess what’s really cool is that I don’t think I have ever not been able to find what I want on Amazon.

I also really like how I can use a wish list to let family and friends know what I like and I like to purchase things off their wish lists as gifts. That is the main reason I will check Amazon first, before going anywhere else.
