Would echo what the Irish guys above have said. Between John Gunns camera shop and www.thephotoshop.ie you should find all the things that you need. I also use from time to time but not that much anymore www.macodirect.de.
The UK online shops mentioned in a previous post I haven't used in a good while as some of them don't ship liquid chemicals outside of the UK and their minimum order amount and shipping charges are a little too expensive.
Theres a good group of us that get together a few times a year to show prints and take pictures etc. Feel free to join us once you get settled.
