March 2012 update
We added some new stuff in the last days:
- Amazon China : Now you can see the price of products from the Amazon China store
- Availability in ES, IT, CN stores is now shown directly in search results (the list of flags on the right)
- Other formats and versions: When you are looking a product (mostly books), we show alternate versions, old editions, etc.. This includes Kindle version if available (sorry, no price for Kindle version, so no ebook comparison)
- Price evolution graph for new products: A classic of good old Pricenoia, returns bigger and showing price evolution in every country, in your currency. Price evolution graph uses original country price info and todays exchange rates, so it does not take into consideration currency fluctuations, just original price changes.
