Take pictures of your records if you are selling them online. EBay and Craigslist are the two most popular sites that users visit to buy and sell all kinds of items. EBay draws a small fee for sellers, while Craigslist listings are free. Both sites require a quick registration, including an email for contact purposes. Take clear and close up pictures of the records and covers, as well as the liner notes. List your item using key words that will make it easier for users to find it. Use words such as disco, LP and vinyl, as well as the name of the artist, year of the recording and the album title. Set a reasonable price and calculate shipping. Some users will not bid if either of these costs are too high. Include what condition your records are in so as not to mislead the interested parties and potential buyers.
Open a table at a local flea market or swap meet. Flea markets draw many people who love to shop for antiques and hard-to-find items. The cost of doing this is usually inexpensive -- usually under $20. Some flea markets require a short registration form if they are only open for a few days a year, so check in your local area to see the specific procedures.
Have a yard sale. Yard sales, like flea markets, are open to the public and welcome all types of people looking for a good bargain. Set up tables in your yard and garage and advertise with signs along streets close to your neighborhood. Price your records reasonably for potential buyers. If you have nothing else to sell, ask a friend or neighbor who is having a yard sale if you can set up a table to sell your records at their sale.
