We recently decided to downsize our home here in Singapore and as a result found ourselves with quite a few items we wanted to sell. I tried e-Bay but found it to be quite cumbersome. I ultimately decided to use Evernote. I used Evernote on my iPad to take pictures of the items I had for sale, and then recorded the dimensions and price in the note field. For electronics I used Web Clipper to take snapshot of the manufacturer web sites listing the technical specifications and pasted that into a note along with the picture I took from my ipad. When I was done, I had a notebook with all the items I wanted to sell, the technical specs and the price.
I then made the notebook Public and created a memorably bit.ly link to the notebook and referenced the bit.ly link the paper flyers I posted on various message boards and my Craigslist listings (one point to note here Craigslist doesn't like url redirection so it complained about bit.ly references. I worked around that by simply embedding the link in an image). Bit.ly lets me track clicks to the notebook. When Items sell, I use Skitch to update the image showing the item was sold, or simply move that item to another notebook thus preventing someone from calling on items I have already sold. As I move closer to our move date, i will begin lowering my asking prices and posting the current highest offer for any item.
In one small project I used Evernote, on my iPad and Mac, as well as Webclipper, and Skitch.
By way of example I have uploaded one of the ads I posted on Craigslist. If interested the bit.ly link is http://bit.ly/tbmove
