We had the same experience as lets-retire.
We went on one of these "free vacation" group tour things in Fort Lauderdale to get some perks in the Bahamas, and we were filtered through more and more aggressive salespeople, each with a price reduction, until we were looking at a price one-quarter of what we'd been originally quoted. My "no" was final and we escaped.
About two days later we ran into one of the couples that had been in our tour group. My wife, who has no guile and no tolerance for guile, asked them how they'd fared.
"Oh, we bought in," chirped the husband.
"What'd you pay, if you don't mind my asking?" my wife replied.
He beamed. "We knocked 'em down a good bit, from twenty grand to fifteen. What about you guys?"
My wife gave him a sad smile. "Well, every time we said no they lowered the price. The last offer they showed us was five thousand. We said no and they let us out."
The guy's mustache worked and I thought he was going to come out of his chair.
Later on, when my wife and I were alone, I bought her a drink. "You know you ruined that guy's vacation, right?"
She shrugged and raised her glass. I clinked it.
