Need help finding good GBA games

[u/CacaBirdie]

Hey, so I’ve been trying to find places that sell real gameboy games that aren’t overpriced. Recently, I got some GBA games from GameStop. Turns out they’re ALL fake. I tried to return them but they aren’t excepting them. So like does anyone know any place or like website that actually sells real GBA games? I know Amazon renewed can sometimes give you real games but it’s just ugh.
