Wow- That's $400 to $500 more than the US, I wonder why?
Well certainly the 22% VAT is part of that.
When I was shopping for a MacBook last year, I found the best price in Saturn--somewhat lower that in MediaMarkt (apparently owned by the same company) and less than from the Apple dealer. It's worth shopping around. Allegro is another source, as often Poles returning from the US bring along new MacBooks to sell at a profit.
