Where can I find the cheapest laminate flooring?

[cruusshed]

.....I need to cover cracked ceramic tiles in my kitchen - very large area - too expensive to take up and relay - also a temporary measure as we will move in a couple of years.

This might not be helpful but...

I'm having an extension done and need a temporary floor in a room. I was going to get a cheap, laminate but found burts.co.uk that do some very cheap Lino floors, after getting some samples I'm going with this, much cheaper and warmer than a laminate and won't cheap, split etc...
