I thought the purpose of that was to let them avoid price matching on certain items despite having price matching policies. I have never heard of one budging on this. Have any?
It is so the manager has a policy to fall back on to say no. It is just the second round of negotiation.
I am not saying everyone will play ball, but managers whose pay is a function of sales likely will. Have you ever negotiated buying a car before? Indicating you will let corporate know they lost a sale by not budging on price will almost always win the negotiation with managers who think they can just be lazy without consequence.
In the standard retail environment, I have definitely had businesses price match products with the same specs but very slight SKU differences, you just have to be open about a willingness to forego the instant gratification because that is the only service in person retail provides today. That might mean actually completing the sale online and then asking again. They know when there is actually a material difference to the products.
Businesses that are legit monopolies will not budge.
