Blockbuster and the retro market

[wiggyx]

Today while waiting for my train I saw a poster in the window at Blockbuster. Apparently they are buying old games now, SNES, GBC, PS1/2, NGC...

This got me curious. Have they been doing this before? Why (Any BB workers around to share some insight)? And do they do it on a global scale?

Oh yeah, this was in Denmark.

Their trade-in prices (Store credit only and in DKK) for the curious

And in case they pull the pdf, here's the link I got from scanning the QR code on the poster.

I believe they did (or maybe still do) buy used games here in the US. I wouldn't know for sure if they still do or not since about 99% of them in my area have folded in the last few years
