Flexible Power Cords

I'm looking to replace my bevy of power cords with a consistent set. 

I want flexible cords for obvious reasons. I'm tired of those power cords stiff as a stick.

I need length up to 3m. I'd buy Nordost now except that they don't come in anything greater than 2m.

I am looking on the budget end. (I need eight of them.)

Thanks.
