Hi tmhuud,
Thanks for your interest in our products!
When purchasing physical products (Vienna Instruments Standard Libraries or boxed Software products such as boxed Vienna Suite, boxed Vienna Ensemble PRO), an additional sales sax will be applied (in California between 8,25 and 10,75%). This is because all orders of physical products in our web shop are being processed by our american distributor, ILIO Entertainments.
If you order non-physical products (such as the downloadable versions of Vienna Suite, Vienna Ensemble PRO), Extended Libraries of our Vienna Instruments DVD Collections or Download Instruments, no additional tax will be applied.
If you've got further questions about the sales tax on physical products please contact ILIO Entertainments regarding this issue at ilioquestions (at) ilio (dot) com.
Best,
Stefan
