DS is 3 so only in nappies at night. I use flushable liners and can't seem to buy them anyway round here anymore. I used to be able to pop into any Boots and get them but they have stopped selling them for some reason. I live near a very big Mothercare but even they only sell Bambino Mio or their brand (both of with are incredably over-priced) and even then they only have the nappies, outers and 'start-up sets'. Mothercare don't even sell nappy pails anymore unless you buy the whole kit.
I thought the use a reusables was on the up but maybe not.....
