Folks, I sell small dollar items. Most of the video games I have listed here are priced below $20, most toys under $30. My pricing model assumes that the item won't sell for a full year. Granted, as a store subscriber, my insertion fees for toys are 20¢ instead of 30¢ each per month, as I list everything as GTC fixed price. That's still $2.40 for insertion fees per item, per year. Video game insertion fees are 60¢ per year, at 5¢ a month. I don't include the free listings or promos each month into my calculations. I have to get at least $11.95 per toy and $7.95 per game to break even, including shipping and other selling expenses.
Not every item is best listed on eBay, or even online. Sometimes the cost of selling, particularly shipping, is just too high to turn a profit on a single item. For example, I never list any single Atari 2600 game, unless it's Swordquest: Waterworld, Crystal Castle, Mario Bros., or another rare title that will bring at least $7.95. I sell most 2600 games here in lots to fetch a profitable minimum price. Same thing with NES, Sega Genesis, Saturn, Turbografix, and most other older game systems.
Let me repeat Atari's old marketing slogan for the Jaguar system, "Do the math!" Run the numbers and figure out how best to list the items you have in stock for the most exposure and the least amount of money. The more you list, the more you can sell. Inventory is no good unless it's listed and can be sold.
