When is the best time to buy from Carpetright?

Hello,

I need to replace some of my house's very old carpets with possibly vinyl flooring and was wondering when is the best time to order from Carpetright to have the best deal possible. I was recommended this company by an acquaintance. Has anyone dealt with this company? Is fitting included in the price? How do I subscribe to their newsletter to know about offers, etc.

Any advice, tips, etc. are gratefully welcome.
