Try zooplus.co.uk (there is an irish site, but the UK one is cheaper).
You'll get free delivery if you spend over £49 & an extra % discount for your first order. The food from there is significantly cheaper than you'd buy over here - have a look & stock up. It will take about a week to deliver - I'm sure George can wait!!
It's also the cheapest price I've found for retractable leads (a 7mtr Flexi for £12, they are about €25 here)
What type of dog is he? (for some reason I'm picturing a boxer)
