They do a great job dealing with scams!
With the amount of scams on othe auction places, Jawa does a great job trying to mitigate/get rid of scams the best they can. I have sold and purchased from there and it has turned out well. I had one issue with a purchase and never recieved the product or communication from the seller. Jawa customer service had that resolved quickly and in the same business day they already had my refund in processing. I couldn't be happier using Jawa for PC products.
