I made a horrific mistake (worksheet formula cut and paste with wrong cell reference). The correct ratio is 31%, not 47%. Thanks to Bob Swart for pointing it out.
I should have taken a hint from my own comments in the first article... sheesh...
Still - fact is that the EUR price for Nordics still is 31% above the USD price. That is way out of wack.
You can see the calculation here.
The true cost difference for the Embarcadero webshop prices in Norwegian Kroner is shown in the rightmost blue columns.
