I have used Terapeak to sell some surveying equipment on eBay for my employer. Since the items we were selling were very technical/specific, I did not know how to price them. It is easy to determine what these items cost new, but I did not know how to price them used so that they would sell. Terapeak helped me to determine a good price so that my company got a good deal, but the items moved. Since we had a lot of products to sell, I also helped a couple of coworkers to use the software. We had the business account, so we could have multiple users at a very reasonable cost (about $20/month for what we needed).
