But part of doing what's right is considering opportunity cost.
If buying something would be a win for an org takes up too much organizational bandwidth because of how hard it is to procure, then it's not worth fiddling about trying to buy it.
The org gains a whole bunch of time he's not wasting on useless calls.
when your purchasing 100k+ products having a conversation makes a lot of sense
lots of opportunities to find easy win-win
finding out what the salesmen incentives are and working with them can lead to a good outcome
obviously not worth it for smaller ticket stuff
