saudedell: I think you should still cancel it because as
megajellyfish said, you basically bought the overpriced version of the game. And this is ridiculous, as any bundle should be always cheaper than buying separately.
This is a known thing that happens a lot at GOG when discounts are happening, and it varies country to country.
There are threads here where customers have indicated the deluxe (etc) price was cheaper than buying independently, while others have written the combined cost of separate parts was cheaper.
I have seen it myself many times for games sold to us in AUS, which is why I now always check.
Before Wolfenstein, the last instance for me was Prey about a month ago.
