Rigol will give their Agents some discounts. This is why Tequipment.net could offer free shipping. The discounts to the Agents could even be 40% of the list price I think.
For my real experience, around 2006, I ordered a VS5062D. The list price was 10000RMB, I got it from a local agent who is my friend, finally I got the MSO for only 6000RMB with free shipping.
If you know how lenovo make the computers, you will know why everyone have to wait almost 4 weeks. For the relative expensive product, they will just start to buy required parts after receiving your order, and then they have to assemble those parts and ship it to the Rigol in Ohio from the beijing city, China, finally the Rigol in Ohio will ship it to you. Based on the modern logistics industry and the efficient supply chain of China, they can do all above procedures within 4 weeks, this should already be a kind of miracle.
For reduce the cost and enhance the supply chain, they started to use the ADC form the MXTronics Corporation which is belong to the China Aerospace System, MXTronics participated in the Chinese Shenzhou Spaceship Project. More important thing is, the MXTronics Corporation is also in the Beijing City, thus Rigol can expect shorter lead time to get the required ADCs than ordering them form the US Corporation.
For the cost, as what I remembered, the US gov prohibited to export the ADCs which has the sampling rate higher than 400M samples/s to China, thus Rigol had to use multi-ADCs for higher BW, and they even had to overclock the ADCs. But today, they just need one or two ADCs which can reduce the cost and the noise sufficiently.
What they want is Zero Stock. They do not expect to have any product in the warehouse, and every penny is available for investing.

According to above experience.
In future, I will order from the Rigol's official site ,
if Tequipment.NET has no stock.

All my Rigol orders with Tequipment came from Rigol in Ohio .
I did check with Rigol and it was more expensive
and I needed to pay the shipping and same delivery time.
At this time the world supply is Low,
Why?
