Which analogous cases are you talking about specifically?

And as much as your example would likely result in some kind of conversation with the police, it also highly depends on whether you discounted items fraudulently or if you did it because you specifically were in the position to do so. Your example describes it as though you had full legitimate power to discount certain items up to 100% off. At that point, at worst you would have violated company policy and not the law. You might get fired for it but when a retailer you work for offers a discount you are eligible to participate in it.
