Why would I buy a keycap set from Corsair for $50 when I can get a keycap set somewhere else for 50% or less of what Corsair is charging?

Damn!!! That's a fine looking keyboard(white version)!!

I have a K70 LUX (as seen in the pictures), with a 3D printed white cover underneath the keycaps to mimic the STRAFE's looks. I paid 180e for that thing, and I do not understand what would warrant the price of 50e for keycaps that are no different besides lasting longer (and being optionally white). Even if my current keys were to fade out after some years, why would I drop a full 50 bucks for corsair ones? The idea is pretty good but that price has to come down for sure.

For $90 you can buy Cooler Master MasterKeys S and L PBT, TKL and full keyboard with PBT caps. IIRC it was $80 at release.
