We had a term for some things known as "Trend Setter" pricing.... he was it.
Any time his minions came to my spot the prices always doubled or tripled. I had tags on everything and one of them picked something up and asked if that was the price. I said it was in British pounds so multiply the number by 3 for exchange rate. LOL Eyes rolled back in his head from the math problem and they left. Good riddance!
He was a great source for info. Go ask about a part, get the number/picture of it and then search the swap spots and find it for 1/4 the price. That's how you used him when at a swap. :)
