I have been selling on eBay since 2000 and lately my sales volume and selling price is the lowest it's ever been, and the fees are the highest they've ever been. I too describe in every listing other items I make and do get other business from it.
After a disappointing December and January I have been using eBay for advertising only, a classified ad listing is 9.95 for a month, and is alot cheaper than what I was paying in fees when things did sell. They allow you to edit the ad as many times as you want during it's run.
