my biggest problem as a buyer and seller on craigslist are the people who repost their ads every day. It bothers me so much that I have actually passed on bikes that I was very interested in because of it. it usually takes a week or two at LEAST for a bike to be bumped to the next page, and even then there is a "next 100 ads" link as well as a search function. I have left an ad up for over a month and it was bumped to the next page. I did not repost my ad, yet I sold the bike for my asking price. could I have sold it sooner by "bumping" my ad? maybe. would I have gotten my asking price? maybe not.
