I LOVE CL, I'm addicted to CL, I can't say enough about it! I think it's one of America's best kept secrets! Even being as big as it is most people don't know what it is!
In case those reading don't know:
1. It's all local, you go to
www.craigslist.ORG (not com) and pick your city bookmark it for future use.
2. Completely free, no fees no shipping
3. You name your price and pickup times
4. Free pictures and easy listings
5. Make an account and you don't have to enter your info over and over again! Much quicker to list. (I learned this after selling for months and doing the ad over and over while saying they should have something where you can just hit relist, THEY DO!)
6. It's more than just an online classified, it's a huge website, with childcare sections, employment, forums, etc. (even though I only use it for the buy/sell section) So if you are a childcare provider or pet sitter you can advertise for free in those sections, big plus for babysitters especially!
I sell gymboree on ebay, b/c clothes on CL are impossible! Furniture, baby gear/toys, kid stuff, household stuff etc does GREAT on CL. Clothes=NO
