Paranoid is not the right word. Concerned that they don't arrive in time, knowing that you can only enter 10 codes per day (thus needing 3 days to enter them if you only have 1 account). I am still waiting on mail for Monopoly codes that a seller sent on Oct. 9.
I think you were ripped off. I'm just saying people should be less concerned. If you are worried have the seller email the codes also just in case it only makes sense and I ask everybody about that.
