The point that I was making was that Amazon do collect import tax from the purchaser, and in my particular case, the import taxes are presumably paid to local Customs by the Courier (again in this case UPS) otherwise they wouldn't be cleared. It's a simple formula for the appropriate taxes to be applied to the destination country.
When I've ordered items to be imported from the US or Europe (direct from suppliers rather than Amazon), I've never known how much tax was due until they were delivered to my door by the Courier. I much prefer Amazon's modus operandi where the full cost is up front.
