Just a quick question. I was redeeming some codes for D2, and a few of them say Already Redeemed. I see that they have been used on my D1 account (back in 2015-16). My question is, are they one use only and are tied to my D1 account? Or is there a way for me to redeem them on my current D2 profile. (Also, I used the D1 codes on my xbox account, and the D2 codes on my battlenet account. Both are linked together via this account.)
