Laminate floor

Hey people,
Been away from these boards for a good while due to moving house and now fitting out a shop. I am fitting out a shell of a shop for a hair and beauty salon and have decided to put down that floating floor that locks together on the concrete floor. I'm going for the laminate because I might have to upgrade every 5 years or so.

Most of the prices I have seen have been around $35 per sq metre and this usually includes the roll of foam that goes under it. I wondered if anyone near Croydon or surrounding areas knows of anywhere with better prices. I think I need about 77 sq metres.

Thanks Deb
