Congrats to the winner!
Only being at level 48, there was no way I would have gotten this far without getting the free cards from giveaways and the number of gigs I've done. But, that's the great thing about this game. There might not be cheap deals, but eventually you might win a pack or someone might giveaway a sweet card.
I haven't been checking out the giveaways as much lately but I do go to my usual ones.
