I'm still a bit confused even after several postings. Bear with me, maybe I am slow and I don't want to be (or sound) judgemental, but this is how the sequence of events from, Kris' posting seem to go.
1. Kris has back n forth regarding the book. Mike wants more than $6k, but will not settle for less.
2. Kris, is at $5750, but Mike holds at a bottom line of $6K. For some reason, Kris' wife comes into play.
3. Mike, states, Kris has 48 hrs to comply with $6k figure (His bottom figure).
4. During the 48hr period, after learning that Kris has been mandated by his wife not to exceed $5750 Mike, gets an offer for $7500
5. Kris, wakes up and decides to defy his wife and go for the $6k
6. Mike, informs Kris that he received an offer of $7500 (which he has every reason to believe is out of reach for Kris) and accepts it.
7. Kris, is understandably disappointed and posts here within a few days of his frustration.
8. Mike sells his book for $7500, and gets ready to sail into retirement or whatever.
I don't see what is wrong here. Maybe I'm obtuse, but if it were I, sure I'd be very disappointed and my ass would probably hurt, but I certainly couldn't blame, Mike for accepting the best offer. Especially, since there was no way I was going to match it. If I'm wrong here, please enlighten me. Shit happens. I won't even comment on the allegation that he "lied". To me that is just sour grapes. Kris, there will be other opportunities. No need to disrespect someone you claim to respect IMHO.
Kris, I understand your frustration and I feel your pain, being so close to a treasured item. There will be others and I am sure you will prevail in the end. Good luck!!!
