I have inquired via Baikal
http://www.baikalminer.com via Contact customer service:
baikal@baikalminer.com on 28 October.

They have updated me for the delivery after 10 days. So then i researched on asicminervalue.com where i found this company called Miner Bros Limited shipping within 48 hrs . I am sharing the url for people looking for single peaces like me. https://www.cryptominerbros.com/product/baikal-miner-bk-g28-multi-algorithm-miner

So now i have purchased the product with cryptominerbros, I will keep you posted once i get delivery on the product in Wahsington USA.
