Has anyone noticed that the price of advertising with adwords depends on which currency you pay in? I think I am write in saying that the minimum cost-per-click (CPC) is less when paying in in US dollars ($0.05) than British pounds (£0.04). And, I cannot be sure - but I think it gets even cheaper when paying in developing country currencies - the minimum cost-per-click goes down further. Can anyone clarify this for me? Does anyone play the system ie. British nationals paying by credit cards denominated in US dollars, asking friends abroad to pay their adword accounts?
