eBay’s kid brother, users are able to advertise items they have for sale and browse items being sold by others. The principle is the same, an online marketplace acting as an intermediary between members of the public, but the format is rather different; most items are available in the same way as “Buy it Now” lots, going to the first person who offers a fixed price rather than being bid on by several. Also, the search system is also far more practical and effective, allowing users to search for certain details specific to the item type, such as author name and publication date (if you were searching for books), or even ISBN. The drawback to this system is that it prevents Amazon from having the same kind of flexibility in what can and cannot be listed, in order for you to be able to put an item up for sale there has to be a pre-existing slot for it to be placed in, stacked up with the copies of the same thing being offered by other sellers. They seem to be aware of most products, everything I’ve ever sold there’s been a place for, (and that tends to include some pretty obscure stuff) but it does mean that it’s a bad place to sell unique and ultra rare collector’s items, there you’re better off going across to eBay or a specialist site, hell, odds are if you are a collector you already know all the best places to unload your treasures, though I appreciate you humouring me just the same. One of my favourite things about it, particularly compared to the other trading sites, is that listing an item is completely free, it doesn’t sell and you pay nothing, great for unloading all your cheap junk that’s likely to lose you money on listing fees, although they take a larger cut of the final sale price as a trade off. It’s a good site, has it’s uses, particularly when there’s something specific you’re looking for, but for general stuff I recommend using eBay instead. Try ‘em both, see which you prefer and for what.
