I think the context here is when you signed up for a trial and you have a sales person emailing you every single day, and by the end of the week they start using the "I can only guarantee this price" bullshit. It's just an aggressive sales person trying to pressure you.

I don't know what companies you are working in, but if the service is deemed valuable enough really nobody cares about money as long as it's in the ballpark of what similar services costs. And When it comes to time, yes all projects starts with "we gonna start using this this week" but we also know it takes a year to roll out even the most basic tool in a medium sized organization so a couple of weeks here and there doesn't really make a difference either.

All that matters is if the tool seems to solve your problems – and the price is not significantly different from the competitors and having a sales person bugging you every single day telling you you need to make the decision now because otherwise who knows what might happen to the price – honestly they can just go ** themselves. I make the decision when I'm ready, and if they are deciding to significantly jack up the price in between that period they are just making themself less trustworthy.
