The Wishpot web services allow you to create wishlists, track prices, and collect donations for the items desired. There are 3 shopping APIs: Wishlist and Registry Management, Price Alerts, and Chip in. You automatically become a Wishpot publisher and start accruing revenues immediately. Send email for docs. The main Wishpot site is for tagging items from a toolbar or widget as you shop so that you have a running list of things you want, plus price drop alerts. It also has social features like Facebook integration and friend management in one place.
