Got to agree with Michael, we did our place inside and out with paint bought on offers in D.I.Y.sheds in the U.K., two for one or buy two get one free. Always different offers on and the quality is far better than the local stuff. You can also try Amazon they will deliver but I have no idea what the charges are but they do favour the larger order. Get together with friends and order in one hit. ;)  Just heard Screwfix now deliver EU wide well worth a look.
