What apps or websites have you used to help you save money?

There is no absolutely money-saving APP, only a relatively money-saving APP. Now many Taobao coupon shopping apps can help you save money. For example, Huimaike, Mai Guangguang, Jujube Street, Peanut Diary, etc. You can get coupons for shopping, which is relatively cheaper than going directly to Taobao to shop for goods in the same store. These apps can also make money. If you use it yourself, I recommend Huimaike. Because you join the agent for free, the commission is higher than other apps.
