As someone who lives in the UK, I almost see dollars as monopoly money, I just can't easily interpret the value properly. For example, if something I wanted was $10, I'd snap it up, whereas if it was £5 (~$8), I'd think twice. You'd think it would be the other way around given that each pound is worth more than a dollar, but I guess you just give greater value to the currency you use everyday.
Though I wonder, would you generate more sales selling a product for £6, than you would selling it for $9? And could you switch your pricing from $9 to £9 (~$14.71) and maintain a similar conversion rate?
