I believe what G-string was implying, was " no additional charges" to the end-user, or retail purchaser. They are shipping from Kemper USA store, to Kemper on- line USA customer, free shipping included.
The USA Customs charges import fees to the Kemper USA store, which they are not adding to the Retail price.
Luckily, these will be arriving on USA East Coast Terminals, ( I assume, hope), as their is a "slow down/walk off" type issue on West Coast docks, delaying products from Asia getting to Samsung, Sony, Roland, Korg, distributers.
Another interesting issue would be actual Sales tax. I live in Virginia, and they don't require On-Line retailers to collect Retail Sales Tax, but some states do, and a few more started in January 2015. Again, this would also be required of ANY other On-Line retailer, if your State requires it.
