Sorry that I'm a total newbie in magento.
I have a multi-vendor magento site where vendors can create product. But when setting product price some users often do some mistakes. Some times special prices are higher than original price. I like to check this mistake. I want a validation script so that when vendors (who have limited admin access) create a new product then they should keep a minimum difference between special price and original price where special price is always lower than original price.
Can any body give some hints?
Thanks
