(a) Details of a plan to provide special packaging or special package sizes bearing retail sale price representations should contain the condition that customers will not be provided with such packages unless they resell the package at a price which fully passes on to the purchasers the represented savings or sale price advantage.

(b) A packager or labeler who, in good faith, takes reasonable and prudent measures to verify the performance of his customers will be deemed to have satisfied his obligation under the regulations. If the packager has taken such steps, the fact that a particular customer has failed to resell the packages at a price which fully passes on to the purchaser the represented savings or sale price advantage shall not alone place a seller in violation of the regulations.

(c) Any packager or labeler who determines that a customer does not intend to fulfill or has not fulfilled the conditions of an offer should immediately refrain from further sale under that offer to the customer. In situations where proper fulfillment of the conditions of an offer are in question, the Commission will resolve the issue after appropriate investigation of the facts submitted.
