A Second-hand Computer for Sale
Li Ming
I have an old computer that I no longer need. It's a great machine that has served me well, but I'm upgrading to a newer model. The computer is in good working condition, with no major issues. It's a Windows operating system with a fast processor and ample memory, which makes it ideal for students or anyone who needs a reliable computer for work or study.
Asking price is $200, which I believe is a fair price considering its condition and capabilities. I'm open to offers, so if you're interested, please get in touch with me. You can reach me at [your email] or by phone at [your phone number].
I look forward to hearing from you!
