Unverified整箱囤货前先算「每抽成本」而非「每箱价格」，用单价÷（包数×每包抽数）横向比较，防止小规格包装抽数虚标（如标注130抽实为65对/双层）81% similarUnverified整箱囤货优先看『有效克重/单价』而非包数，很多低价整箱采用『大包装小张数』或克重虚标，实际计算方式为总克重=层数×每层克重×张数，对比每百克成本更准确81% similarUnverified判断实际用量性价比应看'总抽数'而非'包数'，宣传'40包'但每包仅6抽的整提总量可能低于'30包×10抽'的产品，计算单抽成本再对比80% similarUnverified自用囤货优先看'每百抽/每卷'的单价折算，礼盒装普遍比同规格单包散装贵15%-30%，为包装和组合付溢价79% similarUnverified整箱囤货计算「每百抽单价」而非每包价格，各品牌抽数差异大（80抽到150抽不等），单纯比包数会误判，需换算到单抽成本79% similar
