Things like packs and the wands, traps, etc from both the original films and RGB. Especially different sizes like kenner figures, Selects, Hasbro, that sorta thing.
I haven’t gone there myself, but I did see a YouTube review of Charlie’s Custom Toy Shop that seemed quite impressive:
Those look great, thanks! Can’t tell if the packs come with the traps or not. They’re hanging on them but that could just be for show. The Kenner rerelease versions are out of stock too sadly. I’ll keep an eye for when they come back in.
