I needed to get rid of some things, so I wrote real classified ads. With real responses. Under a fake persona.
Results: Sold everything (plus a TV and some furniture) besides the orthopedic shoe; dozens of responses; thousands of pennies scattered around Richmond, VA. Technically my highest netting ad campaign with a budget of $0 and profit of $150 and a few good belly laughs.

Suggestion Scott
Todd with an unintentional pun... or sage financial advice?
Jennifer said no to the church, but bought the slow cooker.
t-shirt
JJ was my motivational speaker, lol.
pennies
Mitchell already had a 5 gallon jug of pennies ready.
Andrew & Emily aren't weird for caring.
This kind stranger and their 500 pennies of generosity.
orthopedic shoe
The only inquiries here were asking about availability with no follow-up. Sadly this one didn't sell. Can't win 'em all. 
space heater
Space heaters don't sell easily in April. I sold this one to a friend in person without the persona.  

Peep other projects of mine.
