"Pioneer receiver $300"
"Dear sir, can you give me the model number?" Translation: I don't know which of 987 Pioneers you're selling - an SX-1980 for a song, or BPC. I would think if you're asking that kind of jack for it, you'd be kind enough to tell us what your actually selling.
Reply: "It is old. You are welcome to come look." Translation: No, I would have to get off my fat butt and look at the back, and I am too lazy.
