I think they need to qualify 'cheapest' because as a Brit I wouldn't have to pay anything (directly) for any of these things.
Now the costs of doing the procedures are probably lower, but I have no idea what they would cost in this country.

Its unclear to me whether figures quoted are prices you pay, or cost to do the procedure. Some at least appear to be the price you pay ("Shetty did it for about $10,000 and turned a profit"), which as I don't pay anything directly, suggests that they need to qualify 'cheapest'.
