Finster, I'm with you on the sales gimmicks. Unlike you, I just don't play the games. I don't say, "what's your rock bottom price." If someone names 2 different prices, I say thanks for your time.
I deal with professional dealers who give me competitive written quotes. One number, no gimmicks, take it or leave it. That's the way I do business. It sounds like you're intentionally dealing with salesmen who use gimmicks, and not enjoying it. Find a professional window shop.

Finster's art of the deal would make a book with very few pages. Not necessarily a bad thing.
I still say the money theme is a tad on the heavy side.
It's just money.
Worth less and less all the time.
And right now there is no my way or the highway in the trades arena.
Companies can't get supplies and EVERYTHING is more expensive (thank you Covid).

Finster, you play hard ball with a gruff attitude with the salesperson of your dreams, they'll walk before they get a pen out.
That only leaves the idiots to deal with.
Remember, it's only money and you need windows.

Blessings,
Mark
