One common way to sell old cassette tapes is on eBay, the Internet auction website. A seller must have an active account with eBay to sell old cassette tapes.
To sell old cassette tapes on eBay, create a listing that contains all of the relevant details, including album title, condition and price. As with other sales outlets, items in better condition generally command higher prices. During the eBay auction listing process, you must write a description of the cassette tape. Providing photographs of the cassette tape is often suggested (and at least one photo is required), as it may help uncertain users make the decision to buy.
