Will there be SMS notification for the price difference of Taobao?

Taobao's guaranteed price takes effect, and I will make up the price to protect the difference, and inform me by SMS or email.

When the price of a commodity is reduced (excluding freight, red envelopes and taxes), according to the provisions of price protection, consumers who buy the commodity can apply to the seller to make up the price difference, and the system will calculate the price difference of the commodity and make up the price difference according to the price protection rules.
