The main reason why Yitao.com is cheaper than Taobao is that it has a set of price comparison recommendations, large discount red envelopes and purchase rebate activities. Yitao.com finds the lowest price based on Taobao, Tmall and other rich commodity groups, and also has various large red envelope discounts for promotion. There are also rebates after the goods are in hand, which is naturally cheaper than Taobao.

Yitao is equivalent to a Taobao price comparison shopping guide platform, which is also launched by Alibaba. The goods on this website are all from Taobao or Tmall. But their nature is different. Yitao itself does not provide buying and selling services. It only helps you to check coupons and rebates. The final order is still completed on Taobao. So after-sales service is the same as placing an order directly on Taobao.

You can add the things you like in Taobao to the shopping cart, and then log in to Yitao with your Taobao account. The things you added to the shopping cart can be purchased in Yitao. After 16 days after confirming receipt, Yitao will return a certain amount of Jifenbao to you. Some products don't have a rebate, but most products will give you more or less Jifenbao. After the Jifenbao arrives, you can directly deduct it from your next purchase.

This is similar to many rebate apps on the market. You don't have to use Yitao. It is recommended to compare more and see which one returns more and arrives faster before deciding which one to use.
