Mashups - Mashing net the web2.0 way

I found this website which is a good example of a Mash-up (or mashups). Aytozon combines data from Amazon and Ebay to allow users to compare the prices of products in both. A good source for online buyers who frequent these two sites.

What is a Mash up? A mashup is a website or web application that seamlessly combines content from more than one source into an integrated experience. Content used in mashups is typically sourced from a third party via a public interface or API. Other methods of sourcing content for mashups include Web feeds (e.g. RSS or Atom) and JavaScript.
