I got mine at Rona, David ... like Lowe's but in Canada (and yes, paid in Canadian dollars too ... woohoo!) I've actually seen laminate as cheap as 79 cents a square foot at a local borg.
And at that cost, if it wears out in a couple of years, it sure doesn't owe me anything.
Having said that ... my refrigerator is on laminate for the last 3 years ... big heavy sucker, and it gets wheeled out for cleaning every week or two, so my guess is the laminate will tolerate a bit of abuse and certainly some weight.
I'd have a nicer kitchen floor but my partner runs a daycare out of our home, so cheap and durable are the two watchwords for us in that regard. I did the shop floor with laminate because I had spare ... wouldn't have thought to do so otherwise.
