This is a better solution compared to other SF pickup apps. First, it supports both Chinese and English, and the price is more economical. Second, although the page design is super simple, but we haven't encountered any errors when using this app (until now), which is good, since other app(s) often encounter system errors during the checkout process.

This is actually the best app when comparing to another two similar function app, but sure they still have room to make it better. Just one to complaint about the suppoting responsive rate, it's too slow. It take about 3 weeks to reply my initial message. We will consider to reinstall the app if the mentioned issue being fixed.
