Unprecedented! JD launched the product comparison function on Double 11: directly displaying the price difference with other platforms. During Double 11, JD launched the "Real Low Price Challenge" activity. After investigation, it was found that the products on the activity page all provide a price comparison function. The left side shows the spot price on JD.com, and the right side shows the pre-sale price on a certain platform. Their spot prices are lower than the pre-sale price of the same product on other platforms.
