$749
World Class 6’ power cord compares to the competition at under $10,000.00 Yeah! Really
Yeah, really. $749 is "under" $10k. So is $50. So is zero. "World class" merely means compared to all free power cords made anywhere in the world. "Compares to" means "compares to" not better, just that you can compare them.
The ad in other words says absolutely nothing. All it does is play on the readers susceptibility to emotional appeals.
The "placebo" canard plays on fears just the same only different. Try and be a little more detached, and I think you will find the logic easier to process.
