It's not hard to make a typo when adjusting prices, and if extraordinarily low are then published to eBay, it can cause big problems. It would be useful to have a check performed when changing a price manually within a SKU or when importing a CSV file, that if any price is lowered by more than say 10%, it will be flagged and the user asked for confirmation before proceeding. This feature is available in Magento and BigCommerce and has been highlighted by a client recently as a disadvantage in Neto.
