Hi rpgman1122,
It is a known issue that the Auctiva store and store window will not pick up price revisions when the price of an item is lowered. This is something we hope to address as part of our Phase II release, which is tentatively scheduled for Q1 of 2007.
In the mean time, when you lower the prices of your items, please file a support request and ask that we manually update your Auctiva store and store window prices.
