What is NOT stated in the policy? ( )

参考解析：

根据第二条that the goods are placed in their original package可知选项A正确；根据that proof of purchase is provided可知选项B：收据必须与退的货物一同寄回，表述正确。根据后文内容的阐述可知不同产品的退换货时间期限不一样，选项C表述正确；选项D：如果24小时内退货，所有产品都会享受全额退款。根据文中内容With a few exceptions, anything purchased from a Joy Market store may be exchanged or returned for a full refund of the purchase price within 30 days provided以及Food purchased from our fresh food counters must be returned no later than 24 hours after the time of purchase.可知生鲜产品24小时内退换货，其余都是30天的时间内，但是少数产品例外，所以D项表述不精确。故本题正确答案选D。
