Word of warning on the NA beers, to make up for the lack of taste in some of them they are loaded with sugar, so you end up replacing one poison (alcohol) with another (sugar). There are good NA sugar free alternatives though, two of my favourites that most people who try them seem to like are Lucky Saint and Impossibrew. Not sure if these are just UK based drinks or not though.
With regards to the price being so high, I think a lot of this is just down to economies of scale, they are producing these in relatively low volumes so costs are high, but the more popular they get, and they seem to be getting more popular, then you would hope costs do come down. Fingers crossed anyway.
