Supplier reps are employed by their suppliers to represent them. Each time you get them to break their rules to get an outcome for you there are consequences. For example, if you get a supplier rep to create a card credit to match unsold form sale product it will eventually effect the card supply model for the business.
There are consequences when you are a supplier rep to cut a corner or break a rule. My advice is to not ask – like with the consequences of firm sale product not working. Bending the sale or return rules for firm sale product can only end in tears.
There are also reps who are lying about their products, they will convince you that they are selling very well which actually are not.Once you got conned better kicked them out of your shop and black listed the company( supplier as well) i have been conned a few times and black listed their suppliers as well
