You want to buy or you want to sell ?
Pretty sure sell, so I changed the title
It could also mean he wants to buy this.
Well, sometimes I see such ads where people really want something, which no one puts online, but some people still might have, so, yes, that’s also possibility.
It’s beautiful! 
Wonder what this would cost. Is it NT$50 or NT$70?
Yeah, I didn’t know how to label it< I’m looking for one, I hope this is ok.
I found, that as a Regular I can edit the title here too, so I changed the first two words from “For sale” to “Looking for”.
Is that alright now?
Perfect, thank you for fixing my mistake. And sorry @insertnameshow for making that wrong assumption! Good luck on you hunt!
