check out Tesco - I know they may not have camera batteris, but I had two (flat) lithium batteries in my car alarm key and I went into one jeweller who said - oh no, lithium we don't do those, you'll have go to xxx jeweller, so like a fool I did assuming they were impossible to get anywhere else but jewellers. 15e each! for the batteries. then popped into Tesco to get something and saw the little f*ckers there for 7e for two or something a lot less (can't remember exact price) - anyway point being, check supermarkets out also before you buy. I'm raging I didn't.
