Taobao is cool because you can get the cheapest stuff possible, or the best quality available, and everything in between. It's all about deciding when it's worth to go up in quality. If you want to do that, it's most likely there. And still a million times cheaper than buying on Amazon or whatever
And everything on aliexpress is on taobao (I think it's the same company?) but 1/2 or 2/3 the price
