Huh?

I don't understand these commercials.The spokesman (we'll get back to him) says that Trivago shows you all the different prices for the exact same room. Why would I want to know that? I just need to know the lowest price. There must be some mistake in the way these commercial are written. He suggests there are millions of statistics leading up to the best price. Sounds too complicated to me. Also this spokesman seems really strange to me. I saw on the Internet that his name is Tim Williams and he's a singer/songwriter. Should I have know that? Is he famous?
