Note: limited time free dlc should be here. It's not a contest, free sample thumb drives, or always free or anything like that. It's something that normally costs $2 and went on sale for $0.
And they were introduced last year for free, went up in price shortly after, and are now free again. This is hardly a pattern or guarantees they are free next year. If you want them, download them while they are available.
I also come to CAG to find deals that I don know about. I'm not subscribed to the Sony blog rss, but I'll assume you could say the same thing about any deal.
Overall, thanks OP. I appreciate when other people take the time to both find and share deals.
