鞋品价格

双十一购物节中大量商品采取降价策略促销，但很多商品实际上是先涨后降，为了观测这些双十一活动商品是否真实降价，本数据集选取了2020年双十一购物节中参与活动的鞋类商品里10个品牌的销量前60的单品，采集了这600款鞋类单品的双十一当天价格与历史最高和最低价，以及历史最低价的日期。部分单品包含凑单价格。

During the Double 11 Shopping Festival, a large number of goods adopt price-cut promotion strategies, yet many of them actually first raise their prices before lowering them. To observe whether the goods participating in Double 11 promotions have genuinely discounted their prices, this dataset selects the top 60 best-selling items from 10 brands of footwear products involved in the 2020 Double 11 Shopping Festival. We collected the prices of these 600 footwear items on Double 11, their historical highest and lowest prices, as well as the date when the historical lowest price was recorded. Some of these items include bundle purchase prices.
