I'd be more inclined to say that "it's out of your price range" than "it costs too much." I got a box and I was pleasantly surprised at how many peppers I got + quite a few seeds. It's actually a really good deal if you can afford it. I would get another box, but it's out of my price range.
[Edit: I just realized that you're across the pond. I guess it really would cost too much!]
