This paper extends the fundamental concepts developed for price-adjusted single sampling with quadratic indifference to sampling with polynomial indifference. The rationale of using indifference curves described by polynomial functions and a method of determining such functions are given. Modifications to the existing solution procedure are also discussed. As a result, a simple but general computational procedure is formulated for the determination of sampling plans which provide probabilistic protections to both the producer and consumer. These results widen the range of flexibility in the application of price-adjusted sampling.
