Regulation & law
70% rule
A plan rule that a participant must sell or use 70% of prior purchases before ordering again.
Also: 70 percent rule
The 70% rule comes from the 1979 FTC decision in the Amway case, which described three practices that distinguished Amway's plan from an illegal pyramid: a buyback policy, a rule that distributors sell at least 70% of previously purchased product before reordering, and a ten-customer rule.
Many plans still include a 70% certification, often as a checkbox at order time. Whether it is enforced is the real question.
