Price on this site is misleading. Really, this kit is around 300€ to buy online.

Price is actually over £300 so the value shown is very misleading.

This pack does not exist. The purchase of "HyperX Fury DDR4 2666 C15 4x8GB" would cost over $ 300. This is very far from the price advertised by the site.
