I just read the new eBay fee structure scheduled to begin on February 20th. In a nutshell, they dropped insertion fees for low-end items a nickel or a dime and raised the final value fee to 8.75% for items up to $25.00 selling price.
From my perspective, this maneuver makes it very unattractive for sellers to list low-buck items on eBay, because the selling cost will take a much bigger bite out of the proceeds of the sale. This means a lot of useful items that could have been listed now won't be. Buyers and sellers both lose.
