So, am I right to see that the only way you can spend real money on these cards is to buy physical packs and use the code redeem in the packs? The listing on the iOS App Store says "Uses In-App Purchases" but for the life of me I can't figure out how to purchase PCoins or anything else.
Also, if you don't mind waiting to be frugal, but you'd like to buy some packs in-game, both Troll&Toad and CoolStuffInc will sell the code redeem cards for ~$0.39/each, which is a lot cheaper than buying physical packs that you may never use.
I'm looking forward to playing this w/ the kids (There's also a PC/Mac client for PTCGO as well.)
