As I have yet to get a really good photo printer, I get my "snaps done" at Boots the Chemist and more recently at PhotoBox.
They give ok results as long as you know that they will try and turn your night shots in to day shots and will throw lots of sharpening in to it.
If I have need for anything large or diffrent I will talk to a lab and pay a bit more.

So the question is what do you do and where? Have you any top tips do you find printing at home easy, better, cheaper?
