I am a big fan of myslabs both as a buyer and seller. Minimal fees taken out as a seller versus the Ebay alternative plus there are no bs returns or buyer not paying. From a buyer perspective you know that the card will be shipped out timely with shipping / tax already factored into the price. Also, you need to prove yourself as a good seller / buyer to get and maintain an account. Only issue is pricing is high and feels like being at a card show
