According to my sources, GameStop (And EB Games since they are the same) as a company does stock the game cards, as does Best Buy and Frys. Individual store inventory will vary of course, but maybe asking an employee there will help, in case they have some and just haven't restocked the floor. To save the expense of gas (DOWN to $4.14 a gallon here this morning, ugh!) I would just call the ones nearest to you and ask if they have any in stock.
I hope that helps! I'm sorry you're having such a tough time tracking them down.
And welcome back!
ETA: Here's a link to the card on
Best Buy.
