I’ve had really good experiences buying and selling on CL. I’ve also had great experiences buying on eBay. There’s a seller on eBay that I tend to stick with when it comes to games. nes_headquarters I know it says NES at the beginning, but they have a lot more than just classic games. And if they don’t, they’re willing to recommend a seller that would. The only downside is that if it’s something that’s coming from overseas, you need to give it a couple months to arrive. I bought a couple PS Pockets from Japan earlier this year, and it took a little over 2 months to get. Customs is a bitch. But I got them so it’s all good. eBay is a really safe site to buy from. Coming from me, that should mean something. It’s not unknown that I refuse to trust anything that breathes.
