US retailer has responded to the increased demand for 3DS title Cubic Ninja by ramping up the game's price.
The 2011 Ubisoft platformer has enjoyed a surge in popularity after a hacker detailed an exploit that gets homebrew software running on Nintendo's 3DS – for which a copy of the game is needed.
Prices had already rocketed on Ebay and Amazon but now Polygon reports that High Street retailer GameStop has also cottoned on.
The chain is currently asking $39.99 for pre-owned copies of the game, although this is discounted to $35.99 for PowerUp Pro Rewards members. Apparently copies were going for as little as $5 just last week.
"As always, our pricing for these games is competitive and is based on current market value driven by supply and demand," a GameStop statement confirmed.
The chain has previously proven responsive to shifting market demand, having sold Wii RPG Xenoblade Chronicles for $90, describing it as ‘vintage'.
Nintendo recently pulled Cubic Ninja from its eShop in Japan. It has never been available digitally in the West.
