With the price of stalingrad being so low I would get it for each account
Here's my idea.
The Moscow account is $12. I could get 1 and add the d9 for$5 so for $17 I could have Moscow with a d9. I would get 2 of these for the kids as it seems to be the best bang for the buck.
For my account I'd get Stalingrad premium for 19 and add the d9 and the hurri2 for a total cost of $30
That way we'd have 3 accounts with d9s to fly together and we'd have 3 accounts total.
That would put me at about $65 for 3 accounts with all having D9s and my account would have the Stalingrad planes plus la5, a3 and d9 and hurri2
I don't see the p40 and c202 as worth paying for premium for.
Does that make sense or am I misunderstanding something?
