Not sue if I understand your post correctly. 0.47uf HK$350 2 pcs (i.e. HK$175 each), but 1.0uf US$25 each (i.e. HK$195 each)? The prices are too close. Given the cap value, I expect the prices should be further apart.
Parts Connexion has 2 kinds of Jensen 0.47uF 630V, one called "Copper foil" @ US$21, another one called "Copper foil paper tube" @ US$71.95. Which one is in DUALXEON's photos? Some Jensen signal cap is yellow (or golden ?) in color, but DUALXEON's are silver, are they different types or just different batch of production?
