So Christmas is approaching and you need to buy some presents for your friends. So good for the idea, but what to buy?
I've created a little web app for that, called Wish-O-Matic. You choose a few things of which you know that your friend likes them. That's it. That app will tell you what would match these items.
The Amazon Web Service API is used, so the products are somewhat restricted to the products they offer.
Give it a shot: Wish-O-Matic
