App prices changes between Marketplace and Checkout

Ok, this is weird and I can't find an explanation. There are a lot of apps in the Android Marketplace that advertise a price but when I select buy and accept the permissions the final amount is different. Usually a bit higher (eg 85p goes to 99p) but sometimes lower. I have seen two 85p apps where one goes to 84p and the other to 86p so it is not a processing charge or tax.

Why?

If not evident already I should add that this is in the UK.

Ahh. That would make sense. I have just looked at a string of apps at the same price and all from the same developer and all appear at the checkout at the same price.

It's kinda odd though there is no mention of this that I have found in the marketplace. Usually if you offer a product to overseas customers priced in a local currency it is the supplier who takes the hit or benefit in the currency conversion. Why make things difficult for the poor consumer?
