When you buy pizza for delivery, do you need to ask about their margins?

"I want X." "That'll be 22.50 with delivery." "Ok."

If the price is fair to you, buy it. View this as another store which happens to have everything. Under the hood they run out and subcontract.

If you're concerned about minimizing the price, you probably shouldn't be using a service designed to charge you for a few minutes' work. The target market for this thing is people who are looking to trade money for time.

It seems to me that their target market is people who read the quote and go "I don't care enough about this to look elsewhere" - i.e. people who care if they're acquiring sufficient value for money+time spent, rather than people who care that they're acquiring the most efficient use of their money.

Wasn't it actually convenient?

I like the one cost quote. Perfect. Things are worth what people will pay for them.

They quote, you either find it's worth it, or not, no worries.

Seems to me, there will be people who value their time low, who will not want to pay so much, and others who will value their time highly and will pay.

Scaling off the latter crowd might be easier to do and capitalize on.

My thoughts exactly. I have no idea what the "tip" is and if it perhaps varies depending on what service I'm requesting, time of day, whether my phone number is even or odd, etc. It would be nice if this was more transparent.
