We bought a new couch awhile back and had it shipped from Homemakers in Des Moines to our house for $75. My father-in-law was beside himself that we would "waste" $75 having something delivered when he has a pickup truck that we can use.
I had to explain to my wife (so she could tell her dad) that it was a waste of our time to NOT have it delivered. She agreed but had to convince her dad, who has been known to just go "do things" without asking.
Driving to/from Des Moines from our house would take 3 hours. Waiting for the couch and loading it would take 30 minutes. Unloading it and setting it up would take another 30 minutes. So, there's 4 hours of time, plus gas just to get the couch to my house. Not only that, but since her dad lives in another town we'd either have to drive there first and go to Des Moines with him or he'd have to meet us in Des Moines, drive to our house, and then back to his house after the couch was set up. Now we have gas for two cars and even more driving time.
To me, saving that time/trouble was worth $75. He was furious that we would spend $75 have someone else do something we could do ourselves.
So, CF, when is spending money to save time worth it?
