The old saying of "you snooze, you lose" does apply when there is a great deal. Ive sold stuff on Ebay and locally on CL, and if you have a good deal, you WILL get emails or calls within 5 minutes , as was noted. The Proper thing to do is to take the first respondent and give them a chance to see the thing and make a decision. All within a reasonalble period. If I have a list of people all wanting to buy the thing, im not going to wait a week for someone to come out to see it first. Now this is the proper thing to do. But because of all the FLAKES out there, if a seller gets a lot of respondents, they will look at the list , and choose who they think is the most reliable buyer. They could care less whos first, or about giving you a chance, if someone else is waving money in their face. Ive jumped on deals before in the past w/o looking carefully, and ended up with crap. I learned my lesson, but I do know if I see something I want, Im gonna make every effort to contact the buyer right away, make sure they know I am Serious, and try to make some kind of arrangement.
