i am an amazon seller from New York, i sell about 1500 used and new books every month. i think that other sellers use a program or something to undercut me by a penny over night, every night. i have 14000 listings and go crazy everyday to match the price, i am getting fed up. is there a program that anyone knows about that i may use to facilitate my pricing, i am willing to pay for it, don't plan on scamming me, i will pay after i use it. thank you frank singig
