Unverified80% confidenceDecision RuleTime unknown
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

Unverified算真实单价要用『总抽数或总克重』除以价格，而非按包数或箱数比较——很多低价箱装单包抽数少(如100抽)或克重低，折算下来并不划算83% 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83% 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82% similarUnverified计算真实性价比要看'克重/每张成本'而非单包价格：大包装标注总重量除以总抽数，优质抽纸单张克重约0.8-1.2g，克重过低（＜0.7g）说明纸薄需多抽，实际不省82% similarUnverified不要仅看'80抽''100抽'比价，需结合克重和尺寸折算单片成本（单片重量=包净重/抽数）。同价位下薄款抽数多但单片薄，真实性价比要看每克成本82% similar
