How can JJB Sports sell Yves Saint Laurent? :S?

I always thought that Yves Saint Laurent was a luxury brand and yet JJB seem to sell vast amounts of YSL clothing? It makes no sense...|||That made me LOL, I know right, cheap JJB selling luxurious YSL?!!!! LOL! If I were you, i'll buy whatever YSL it is cuz you might regret it in the future :D|||Maybe last season's stock or knock-offs. x
