集运便小幫手 (Convenient Shopping Assistant) is a free Chrome add-on developed by Taocarts. This browser extension allows customers to use the proxy payment function without having to open the Princess Payment website. When customers make purchases and confirm their orders, they can choose to have a friend make the payment on their behalf. Once on the payment page, the Princess Payment Assistant will automatically pop up, allowing customers to log in or redirect to the official website for registration. If customers are already logged in on the official website, they will be automatically logged in and their information will be displayed in the assistant's pop-up window. Customers can easily initiate proxy payments through the prompts at the bottom of the assistant's pop-up window. Additionally, they can access the instructions and usage flow by clicking on the Princess Payment Assistant icon located on the top right corner of their browser.
