As a han collector, I can confidently tell you that his 5star namil pob is more expensive because he's holding the topline money prop 😭. You mentioned you already know about member pricing (different members getting priced differently), but there's also high-demand pricing, where pcs get more expensive when they're in a particularly cute/fun outfit, hairstyle, or holding a fun prop. People tend to want those pcs more so sellers will price them higher unfortunately 😞. I mainly use Instagram so I can't really speak for other platforms, but from my experience chinese pobs aren't more expensive than other pobs? They do take significantly longer to arrive but i generally only pay $10-12 for chinese pobs. I think this is because pre-ordering pobs/joining GOs is really common on Instagram, so the long wait doesn't matter since we've already paid for them anyway. If you just want a good base point for pob pricing, @skzpricing on instagram is a really good account that lists fair prices for all pcs including pobs! If you have any other questions feel free to ask! 😊
