Don’t think SFK has much overhead Wearhouse space, just my assumption I have no facts to back it up.Wouldn't be surprised if Luyuan is doing the packing/warehousing for them. This has me wondering.... the potential for a US warehouse for Luyuan where they ship out of the SFK warehouse? I think many of these shops have some type of deal going where they share warehouses on overseas/us.
Now to stir up the pot even further, you guys need to see this thread: Docan Real Grade A cells 280K with test report for $132.00 delivered & shipped from the US warehouse BUT... there is a catch: https://diysolarforum.com/threads/docan-power-us-warehouse-lf280k-review.65429/
