Beware of sales pitches, whether from individuals or in ads, that urge you to get in on the ground floor or to act at once. Avoid being pressured to make a quick purchase at a “low, low price,” to buy now because “tomorrow will be too late,” or overreact to being told “don't be a fool,” or “when this becomes public knowledge people will be lined up to take advantage of this golden opportunity.” Shady promoters may even offer to have an express delivery service pick up your check. They don't want you to take time to think, read the small print, or talk to others.
