RepArchive TOP is the first website that lists the best selling items from Taobao and Weidian.
Taking a look at the best selling item is a great way to find items that are priced well and of high quality. Especially if you don't want to do your own research, this is the best place to find what you're looking for. It doesn't get simpler than that.
It allows you to choose between different time frames to see the day's bestsellers, the week's, the month's or the all-time best. That should give you plenty of items to find what you're looking for.
