I joined several years ago, but so far have only purchased things like fabric from them. As far as I understand, they charge 20 cents for a posting plus 3. something percent of the selling price (shipping not included). I'm not sure how the money transactions work. I know they can take it directly from your Paypal account, but I'm talking about how people pay you.
Etsy is sort of like ebay, except mainly for crafters and there's no bidding, just a price listed. And you can buy immediately, no waiting like on ebay. BUT ebay handles the money, you just worry about shipping. Their listing is more expensive as well as their cut of the selling price (which is why the auctons are more profitable ).
I'm going to give etsy a try sometime before the holidays. I'll let you know how it turns out. But do go and take a look. They have some amazing things at reasonable prices.
