"Original Ds games are ridiculous now! why?"

So I have been trying to get some ds games of gen 5 for nostalgia purposes and guess what? Black and White are $60 and and Black and White 2 are almost $100. What Gives?!?Diamond and Pearl are still sort of cheap in terms of gen 4, but Heartgold, Soulsilver and Platinum are $80!So why are these games going up in value all of a sudden? via /r/pokemon https://ift.tt/30UpynU
