Just bought two sticks of this.
£11.99 a stick or £11.69 per stick if two or more purchased at the same time.
Plus, if two or more purchased, sticks will be despatched in matching pairs.
Seems a real bargain to me.
They also have PC6400 RAM for £13.99 per 2GB.
I use Quanti as a cashback site, which pays 1% with 7dayshop.
