AliExpress is one of the most popular online markets with more than 100 million items available for purchase. With the rise in its popularity, the company behind it, Alibaba Group, had created an official app for Android and iOS long ago. The main purpose of the app was to keep customers updated about new deals, send order status updates and offer mobile-exclusive price cuts. There wasn't an official app for AliExpress for Windows until now but yesterday, the first version of a Universal Windows Platform app was released for Windows 10. But there's a catch.
