I'm soft-launching Rankique, a web service for you to keep a simple wishlist of items you wan't to buy.
We help you save a lot of money, by notifying you whenever some of your wishes become cheaper.
Feedback is very much appreciated!
(The service uses data from Amazon.de, if you're not living in Germany, you won't get much value from it. But please give feedback on whatever you think could improve the service.)
