If like me you live in the UK and you also have a Google Adsense account, keep the money in the account until the $/£ exchange rate comes down a bit. I got my first payment from Google and the money I got for it was pitiful (especially considering it took me a year to get up to the limit).
Aditionally, I also belive if you are an advertiser in the UK you are also getting done by, 1p > 1c by almost twice as much. Therefore unless Google opperate an exchange rate program where my advertising gets a higher prominence than the equivilant "centage" advert then us UK advertisers are getting a raw deal.
So for now I have suspended my adverts that I sell and I am going to keep the money in the Google account for longer if I ever recieve another payment.
