Bullshit you had another offer! I sent you the “I’ll take it” message AND posted on the thread 5 - 10 min after your original posting. You posted “stil available” 8 hours after your original posting.
I’m not really gonna debate. You offered $500 and I moved on as seen above. You’re free to do that, just as I’m free to accept someone paying asking price. Sorry for the mis understanding. Maybe you had a typo with your first message.
