I've used several repricers, it's a must when selling competitive products with a large numbers of skus. One thing I'll note is that there's up to a 15 minute delay before a price change takes effect. Also, Amazon will often "suppress" the buy box if no sellers have a good price. You can still buy, but there's an extra step needed. "Other sellers", then add to cart.
