Beware of These Risky Sales Tactics That Are Doomed to Fail or Backfire

True story: Recently, my daughter was at a major brand car dealership with her boyfriend, intending to purchase a pre-owned car. Note I made up the numbers for the sake of my daughter's financial privacy, but the takeaways are still the same. The dealership asked for, let's say, $26,000 "all in" for the car, but my daughter had already decided that $20,000 was the most she would pay.
