The techie that set this up for me said it would update every 30 minutes but is seems to be varying between 45 minutes and a hour and a half. There is a time stamp on the bottom of the pages that tells you when the availability was generated. If it is more than a few hours old please let us know so that we can check into it.
We hope that this makes ordering with us easier. Please let us know if you any suggestions on improving this process.
