Their main saving comes from purchasing their house-blend, which is 17p per cup if you buy 100 at a time. Their other blends are 21p-25p per cup. Nespresso prices are 29p - 33p per cup on average. The Fine Coffee Club is definitely cheaper, though not by a country mile unless you buy their house blend in 100's.
I bought their house blend. It tastes not very good. Their dark roast - a more expensive blend - is quite unpleasant.
I can only assume that the word Fine in their name comes not from the quality of the coffee, but from the degree to which it is ground.
