I haven't got a clue if Denorex is better or not. I suspect they are fairly comparable, but who knows? There have been a whole series of totally unremarkable products advertised as "only available in Canada" on Canadian TV for years...basically as a joke, because no one in Canada really gives a damn if something is only available in Canada, but it's fun to pretend that other people (like the British) are desperately jealous because THEY can't get it! :-)

There was a long-running Red Rose tea ad based on that premise for many years. The scene....

STUFFY, POMPOUS OLD BRITISH GENT:

"By Jove, Rachel, this is simply marvelous tea! What brand is it?"

HIS STUFFY, POMPOUS WIFE, RACHEL:

"It's Red Rose tea, Winston. Eddie sent it from the 'colonies'. He says it's only available in Canada!"

WINSTON (looking flabbergasted):

"ONLY AVAILABLE in...Canada???? (shaking head in exasperated wonder)........Pity!"

This is all, of course, nonsense. Red Rose tea is available almost anywhere in the world. And as tea goes, it rates about a 4 out of 10.
