eBay seller djbenzsl has a lot of nice sealed items. Highlights I haven’t seen many times include a sealed Trolls on Treasure Island and several sealed Black box games.
eBay seller topol777 has tons of rare games listed in their store. From staples like Flintstones: Surprise at Dino Peak, Bubble Bobble Part 2, Little Samson and more. They’ve also got several repos and tons of unlicensed stuff.
