What are peoples thoughts on this? Allowed or no? Most forums I've been on frown on it but I didn't see anything that specifically addressed it in the marketplace guidelines. Many issues can pop up when dealing with a middle man who may or may not have any authority to negotiate price or know specifics of the item, etc.

This is the reason I ask:

Anyone in SoCal interested in a Remington Model 51 .380? A friend has one that she's looking to get rid of. It's been appraised for $300-$350. She would take $200. PM me if interested.

I reported the thread as the user only has one post and it was not posted in the marketplace.
