Selling etickets (paperless tickets that take the place of conventional tickets) that you don't want or can't use is a great way to make some extra money and rid of something you have no use for. The advent of online-sale sites has made getting rid of unwanted property very simple. Whether you have ever sold an eticket before, you will find that the process is not as intimidating as it might seem at first.
Place a listing on an online auction site such as eBay. This lets potential buyers examine pictures and descriptions of your etickets and bid on them. Doing so widens your pool of potential buyers and allows you to post images and lengthy descriptions and even links if appropriate (e.g., if you are selling etickets to a concert, you can link to the band's music or videos), so buyers know exactly what they are getting when they bid.
Post an ad on the local website of an online marketplace site such as craigslist.org. Craigslist will enable people who are in your area to peruse the listing for the etickets you are trying to sell.
Place an ad in a local newspaper or community newsletter. You can generally do this online, although placing an ad via phone is common as well. This will ensure that the audience that sees your ad will be in the area and able to contact you easily.
Post an ad on Twitter, Facebook or other social networking sites that will allow to target friends and acquaintances who may be interested in purchasing your etickets--and who could access them very easily via email.
