I got sucked in last November and ordered some items in this promotion. Four months later I'm still waiting for the items to be delivered. One supplier called CARSUN 01 store took my money and claimed the goods were delivered and refusing to enter into a dispute situation.
If you ever use aliexpress follow up the purchase on "my orders" as the many suppliers will not email you as to the progress (or NON- progress) of the order. In my experience the "Singles Promotion" is an excuse for many criminals to rob you of your hard earned money and there are few (if any) steps you can take to rectify the situation.
