I’m auctioning off out/away (? Non native speaker 😅) my old-ish gaming consoles and this person is asking about a unit’s serial number. Why? I mean, I put up more than ten images of the console from various angles and such… What’s the significance?
“I’m auctioning off my gmaing collection” (many items) OR
“I’m auctioning my gaming console” (single item)
Oh, interesting! I haven’t heard “auctioning” on its own.
