"Business telephone sold for $25 for parts only because I couldn't test it."
If you sell it for a low price and it doesn't work, do you refund them? If so, you might think about selling it for full price and just keeping that same practice in place. It's a little bit scary to sell things that are untested, but even things that you test don't always work after shipping.
Thanks, I sold it at a discount untested "as is/for parts or repair" with no returns as a final transaction. Good thought though. They'd usually sell for $50-$60 so it's a tradeoff for me on the revenue and the buyer on the risk side.
Ah! Makes sense if you're not accepting returns. Keep up the good work!
