Hello, I am the owner of Taobao, and I have been rolling in Taobao for more than 2 years. Sellers have different marketing methods. Some sell more with less profit, while others sell more with less profit. But according to what you bought, the first Tmall was 6 bottles 128 yuan (the total grams are unclear). Suggest asking customer service. The second one is Taobao's, with 6 bottles, although one bottle of 28 yuan (6 bottles are 168 yuan). It is best to choose Tmall to buy nutritious food. Personal advice! I hope this helps.
