1. Ridiculous shipping costs. 2. Selling used cobs. I enjoy my MM as much as the next guy, but, really? And, no, throwing a couple into a lot to pad the numbers doesn't make the group more appealing. 3. Too few or out of focus pictures, especially on the name or logo. 4. Unproven assertions in titles ("Possible Dunhill!") to gin up search results. 5. Has that antique tin been opened or not? 6. Sellers who "forget" to combine shipping - especially when they realize they screwed themselves with a bad listing title (had this happen when I nabbed a Sav and another pipe for next to nothing). 7. An item gets no bids, so you re-list with the same description, pictures, and price. What do you think the problem with the first one was, genius? Yours?
