The difference is shipping from the us to shipping from china. From the us you pay 200 dollars for a 1 dollar arm processor due to shipping. From china you pay 4 dollars in shipping for a 10 cent processor. Apparently buying arm processors in china is not reliable and of course you wouldn't buy a RISC v processor in the us due to shipping costs when shipping from china is 50 times cheaper.
