Expensive wax?

[Joeauger]

I have just been looking on clear your car and saw some wax's over £100. (on other websites over 1k)

I was just wondering are they really worth the price?
What do they do extra to have that price tag?

I've used Blackfire's carnuba wax (bought as the Wet Ice over Fire Kit) the wax is expensive on its own but brilliant to use, it does work work better on darker colours, I'm currently thinking of going for the Werkstatt Acrylic Kit over at polishedbliss for my Polar White DS3 as its one of the best for lighter coloured cars and very easy to use.

not tried any others except for Menzerna stuff.
