Hey Donny G,
I used to be a sales trainer and have quite a bit of knowledge in that area. I'd say yes, definitely to your question. The similarities are amazing. I'm not sure about backhanded compliments, but putting your client on the back foot is used a lot. However, rather than the negative side of PUA, the positive sides of PUA fit right in with sales. There shouldn't be any need to be anything but helpful and honest in sales and I guess that should be in your Game as well.
Amoggin the competition when you see them works too
