If you’re looking for a bargain on a product or service, you can often find one on Craigslist. Power searchers who know how to use Craigslist save time by using the service’s advanced search features. When you view an ad that interests you, you will find a Posting ID number, sometimes called a sale number, near the bottom of the ad next to the words “Posting ID.” If you’d like to find that ad quickly in the future, save the number and look for it using its Posting ID.
