I don’t know where the tax liability is determined.
I don’t know if this would be Europe based in which case VAT would be at the rate of the country of sale and the Czech Republic is in the EU and I don’t know what their VAT rate is.
Contact sales (at) avast (dot) com and ask for clarification, whilst your at it, ask about renewal discount as there used to be one (won’t hurt to ask).
They either don’t have Avast or they do not show it on the web pages, the one I did find just took me back to the Avast
licensing page at the same price.8-((
Well, the rate was 19% until the end of the last year, it’s 20% now in the Czech Republic. So, the web page appears kinda outdated. Other than that, there’s really no way around it. For refunds/deductions info, see here.
