I reserve the right to adjust, change and improve anything about @dstors - you obviously haven't read the whitepaper where it talks about rates between 3 to 7.5% depending on various factors. A lot of factors, actually. Only the seller pays, never the buyer. High volume and dollar amount sellers will get discounted fee schedule on a sliding scale. The fee will be collected upon transaction completion.
If this is what you call competitive, then I'm happy to tell you that we will wipe the floor with those guys. In short: I'm sure.
