as one who does not have a credit card to use for computer gaming and i rely on the gift card you buy in the store..
you can only redeem one at a time so there for you loose a chance to any of the purchasing special offered in the game... as well as not being able to purchase a years subscription..
why not make the redemption a little different.
allow for 4 slots so one may submit 4 authorized code at one time. so if i should input 4 authorized $20 card codes i would be able to purchase a years subscription or be able to get in on a special offer on crowns. as each card is individually authorized when you purchase them you could place a $20 card and a $10 card in the slots and you would get $30 worth of crowns as the coding on each card is synced to the cost of the card. since you already have the coding for the redemption in the game the replication of it to make a multi slot function would be rather simple to execute.
i have stated the problem and have given a solution.... how about professor what do you think about it
would make it a lot easier on me and lots of other young wizards.
