I recommend "My Circle" which is a new start up. It is a local social network application for people who lives in the same neighborhood. It is free and all the users are anonymous. It is alternative to Craigslist.
It is available on Android and Appstore. You can search it with "My Circle"
At this time, no. Craigslist does not charge to list cars or any other items for sale. The only thing that Craigslist charges for is job postings, and this is only in some cities.
Depending on where you live, craigslist or postings in newspapers are a good place to start. If you're looking for more formal options, check out monster.com or any other job search site.
According to a google search, used car classifieds are free. Most all classifieds other tha job postings, or adult material are free.

Cell phone cases can usually be found at any little swapmeet retailer. Postings on Craigslist also find themselves a plethora of casings for sale just for your own pleasure.
Yes and no . You tube allows free postings of videos of just about any thing you can do . Yo tube will charge you for some of their content. Both sites carry similar postings.
There are many job postings online, or in your local newspaper. If you have any water power plants around you, you can go in and ask them if they know, or have any jobs.
You can check online websites that contain jop postings such as jobfinder and monster job and you can also check craigslist and employment section of local newspapers.
Ebay, craigslist, or any online store. You won't find any at retail store like Hallmark.
The FAA website has their job postings listed at jobs.faa.gov. You simply have to search for the job you want and it will display any open postings. Good luck in your job search :)
Any thrift store (Savers, for example), craigslist, ebay, etsy, sites like that.
