Took dupes to Gamestop over the weekend. Got $350 for what dupes they would take.
Spent about $100 of it. Bought Gear.Club Unlimited (NS), Robinson VR (PSVR), Earth's Dawn (PS4), Lost Planet 3 (360), and Furu Furu Park (Wii).
If Gamestop will ever start taking PS2 and Atari games, I'll probably get a ton more trade credit.
