No there is no monthly fee. Only a small fee when you sell an item. And you can list as many as you want and even leave your items there without ever having to relist if they don't sell. Now they do have a booth charge for those who want to advertise more and do more with their booths, but I checked it out and I wasn't interested in wanting to do that. Just the simple booth is all I wanted. If I sold a lot of things, then I may consider it, but for now, their basic booth is super enough for me. Just check them out and try to get acquainted with their site first, that's what I did, before I started listing my items. And you also get up to 6 free photos to list; it's a pretty easy auction site, and so much better than that nasty eBay, which is constantly hounding you for more money in always changing their rules and guidelines to gouge the seller.
