any advice?
Don't make duplicate "for sale" posts in Main and B/S/T for your first and third posts within 30 minutes of registering.

Say hi and introduce yourself.
Thumb through the stickies . . . like
this one over on B/S/T that specifies that you're required to post your location on B/S/T threads so readers can tell if you're within a reasonable distance for pickup instead of shipping.
You're not exactly making a great first impression, Dave -- unless you
wanted to imitate a scammer/spammer.
