EU PSN DLC compatible with USA PSN games?

I'm wondering why you bought the American versions of the games in the first place, instead of the European copies?

Cheaper plus they had the spend $100 promotion and get $15 credit which the EU didn't at the time.  I saved like €30 getting the complete cod4/IW edition on the American store.  So even though this sale will cost me €2 more on the American store I still get a better deal overall.  

 

Horizon was cheaper so even though I won't get the $5 discount I'm still getting it in dollars which is cheaper then the EU version.  And the full game at launch I got the same benefit.  I guess I'll just have to suck this up. 

You can download the US DLC though. Why not do that?
