All depends. Once again you could be right but I could also argue under the theory that "once you make a sale you close and get your ass out of dodge". Because things can and do change.
Keep in mind that an open offer not taken can be withdrawn. Or new information can come up which makes it less attractive or gives someone a reason to change their mind. I offer this not as specific advice given the topic but more generally that there are deals that are lost by "dicking around".
I've both seen this happen to others and have had it happen to deals I have done.
In one case Se______a Capital wanted to buy something that I had. I decided to go for a higher amount. Something happened and then they didn't want it at any price. Not even the original offer. Not at all.
Same technique I had used for years that never failed. But it failed in this case.
But there is a difference in my case. It's part of my business to sell what they were trying to buy from me. It wasn't a one shot deal. So I could afford to employ a method that had worked for me for years and be wrong in this one instance.
