Selling jerseys on craigslist?

[Jason]

Im going to sell about 3 NBA jerseys on craigslist. Should I put them all in one Advertisement or separate ones for each jersey?

Representing scarcity is a common advertising strategy, people are more likely to take action if they believe it's the last one available, it might be more of a logistical headache, but advertising one at a time might be considered, might have to change up the ad title, etc. each time, maybe wait a week between them.
