GameStation is closing its doors? Wow, that's a shame.
Still CeX will be on its feet, I suppose, though CeX doesn't offer to sell retro games like Sega Mega Drive from years ago, so yeah... Buying online is the way to go!
Blu-ray may very well be the last disc-format before it turns out all to cards or digital-only.
Edit: With all the unsold games, GameStation, GAME, GamePlay and etc could very well sell them over at Amazon's Marketplace or eBay.
