Maybe little interesting story: bought Fifa 18 at BF sale, $4.01 left in my wallet.
When I saw info about NA holiday sale, logged on that US acc again to see it...
There was nice message waiting me - $10 redeem code valid until end of this year.
When I saw that plus price is $23.99, tried and made it to activate 2 days trial.
Now I only needed to buy one more $10 gift card and my wallet was - $24.01 - perfect!
