I used this link to fetch the pound to euro exchange rate on a daily (nightly) basis:
http://www.google.com/ig/calculator?hl=en&q=1pound=?euro
This returned an array which I then stripped and used the data I needed.
Since the first of November they retired iGoogle resulting in the URL to forward to: https://support.google.com/websearch/answer/2664197
Anyone knows an alternative URL that won't require me to rewrite the whole function? I'm sure google didn't stop providing this service entirely.
