The Joyful Trade That Begins in Naruto

What is the definition of a transaction?

A transaction is, of course, selling something to someone at the highest price they are willing to pay, based on what they need.

"Isn't that just being a greedy merchant?"

"What do you mean, greedy? They need something, and I give it to them. Isn't that mutually beneficial?"

"How is it mutually beneficial?"

"For example, this stack of 100,000 yuan."

"And then?"

"I'll give you the 100,000 yuan, and in exchange, you'll sell me the last shred of your dignity. Deal?"

"..."

"Not interested? Then you'll have to pay more!"
