Trade or sell

Here a nice stamp I do have. I don't collect this country or topic so I don't need it. Do have a lot of stamps I don't need just like you and other collectors. You can exchange or sell it. Now there are a lot of places to sell stamps. When I talk about the WWW . What is the most used site to sell stamps? And what is the best?  I have no idea. Ebay, Delcampe, Bidstart, Wensy are some I know. Here we have Marktplaats (Marketplace) also an Ebay company. Think for stamps you need a site which don't charge any money for your activity, because mostly you talk about peanuts. What do you think or what kind of site do you use to sell stamps?
