Now that bitmain has a facility in California maybe they are able to ship small batch orders stateside now?
Sounds reasonable, but this batch is coming from China based on the tracking. "Shenzhen, China"
Don't get your hopes up on 2 days. Often times it gets delayed because it has to go through an export process to get out of china and an import process to get in the USA. If your shipment get picked for extra screening, expect your package to be delayed even further. As long as your package isn't selected for screening, you should get it within 5 business days. At least that's what experience I've had living in the southeast.
