This trick has personally saved me many hundreds of dollars. Thank you Dan for sharing it in the seminars and thank you even more for not sharing it on the DDMS.
The real jerks aren't those that light the match but those that pour the gasoline. It kills me when I see someone blatantly, explicitly, explaining something like this trick in an online forum that anyone with Google can easily find and when you gently chastise them for their behavior they will stupidly/Innocently respond that "they already saw it hinted to somewhere else so it's obviously an open policy now". No deal got killed with one mention on one forum, It's all the reposts that get those forks sharpened.
