I have multiple CED apps and this one they appear to have stopped all investment into. There is no bulk fix feature like in their other apps e.g. Walmart app allows you to assign the default DVD rating where as this one doesn't. The results are clear as I have over 400 items listed on Walmart but only 21 listed on Bestbuy. Save time and money and just list the Bestbuy items manually as this App does not help at all
