Many countries have different charges for visas. If you have an Irish passport and want to go to India as a tourist, you'll be charged £42. A UK passport you'll get charged £82.
Best thing to happen lately for us brits is the free transit visa for China. You can visit Beijing for 72 hours by flying LHR-PEK-HKG. You can then come back for another 72 hours. Far easier than arranging a visa up front. I've been to china twice this year using that method.
