I never knew it was possible to buy a single computer directly from a Chinese computer factory without ordering it from a warehouse, electronics store, or website like Aliexpress or Alibaba which sells computers. I always thought computer factories only sell and ship many computers at once to a store or warehouse to sell to individual buyers.
The company I work for is premium partner with HP (not sure about the exact programme, I only know it's a very high one), which is why.
At least, that's what they told me.
