No, and I'm glad. A lot of people (like me) HATE 1s undercutters.
Lets sell a master for 30p. Oh but look then someone undercuts you and sets it for 29p99g99s99c or something like that. Did you know that you actually LOSE sales that way as opposed to simply dropping your price by say 25g instead? Theres a substantial amount of the buying population that will skip undercutters and pay a bit more to buy the one that isn't undercutting.
