GameStop is the only place I can find some game for cheaper than eBay or Amazon prices. The problem is only some games are considerably cheaper and they’re almost never in stock, especially at your local GameStop. They’re also slowly catching onto eBay and Amazon prices and increasing how much their older games cost. Look up solatorobo for the DS. That game used to be $15 at GameStop. It’s now $50. However, that is still way cheaper than the cheapest copy on Amazon for $400 game only or $500 on eBay with the case and manuals. I checked a couple zip codes near me in a 100 mile radius, but no copies of this game near me.
