My number one rule for reselling an item on Amazon or Ebay is to make sure you take great photos of your item to post in your ad. Seriously, how many times have you passed up a classified because it doesn't have a photo? I do it all the time. So to make things a little easier for us visual types, there's PicClick.
PicClick pulls only those ads from Amazon and Ebay that have a picture in them, but unlike the standard CL search function, PicClick shows you all of the images at once!
