Why VasY?

VasY ("vas-y!", french for "go ahead!") turns a really long URL from this:
 http://www.amazon.com/gp/product/B000VR0570?ie=UTF8
 &tag=skyrmedi-vasy-20&linkCode=as2&camp=1789
 &creative=390957&creativeASIN=B000VR0570

into something shorter like:
 http://vasy.ca/rs0nh8

Bookmarklet

Drag this link VasY! into your browser toolbar. You can then create a VasY URL from any page by clicking on the bookmarklet.
