Not yet. I bought the Amazon Coins at a 20% discount but I'm going to hold off on the preorder to see if they have a second 20% or 30% rebate deal. $40 for 50 card packs is already a good deal, but getting back 1000 or 1500 coins would effectively make it $30 or $25 for 50 card packs, and that's hard to pass over.
