Morning Excalibur - I wouldn't say it's safe to make such presumptions... some folk will pop back onto their thread to state that their item's been sold, but that's often not the case...
Probably worth clicking on the person's profile to see if they're still an active member (last date visited) and then drop them a private message?
He was on line 2 weeks after posting the ad, seems odd he didn't answer the questions asked of him, he's not been on line since
LOL @ Excalibur. Billy, stop nit picking or I'll confiscate your passport
Nope classifieds aren't removed but it helps if the vendor posts when an item has sold.
