Like many here, I keep checking the Classified Sell section and this is NOT a put-down of the Classified or members selling there. I have bought several items there that I felt were very much "fair market value".
1. Some of the people must really like their equipment and try to sell used items for the same price as retail and in some cases above retail. Not necessarily small town camera store retail, but when compared to some of the larger online stores it is higher. Why would I buy a used item (with no warranty), using PayPal gift or +3%, plus shipping, when I can get the same thing "new" for very close (sometimes less) than what a person is selling it for? In many cases the online store offers free shipping on the item for sale which does make it a lower price. Maybe a better question is why do some people buy these same items? Many of them sell.
2. At the other end of the scale will be a post along the lines of: Brand New In Box unopened, ______ (fill in the blank with whatever camera/equipment you like), less than two weeks old, I couldn't make up my mind what I wanted so I bought several of each. I have decided to keep one of the other models so this BNIB unopened is for sale. Some of these are $200 to $300 below the online store prices. If they are still BNIB unopened, how did the owner decide on another model? Is this equipment stolen or did they get some really great deal from a store that I need to know about? If there is no great deal place, why not return it to the place that they bought it and get a refund? While I can only speak for myself, I would do a little background before buying several cameras, leave them sit while I looked at the boxes, and finally made up my mind. Maybe this is just a case where some people have more money than sense.
Again, I am not knocking the Classified section or members who use it, I just wonder what (if anything) I am missing.
