EA code pre order cancel consequences? Buying on another store

My case is the following, I preordered the game on amazon.de and since they weren't able to provide me with a EA code within 3 days I canceled my preorder on friday night and schwitched to amazon.uk where I got it after 2 minutes.

Now amazon.uk has contacted me that they might not even be able to deliver the game till the 30th. Thus I thought about canceling my preorder and buying it on amazon.de again after I already got my key from UK and DE also would deliver on the 27th.

So are there any consequences if I use a early access code of a canceled preorder and buy the game somewhere else?

I don't think so, there are a lot of people that ordered and then canceled just for the EA code. Probably why other people (myself included) can't get into EA cause the code was wrong or already used :/
