For any purchase, at any amount, where the seller takes credit cards, negotiating the 2% is becoming common. Not from major retailers, but for those with a direct vested interest in making the sale.
Doesn't work with most major retailers. Brings up a very interesting subject for me. With a retail background in one of the (then) largest companies in the world, management controls went down to the local level... with the store manager having the authority to make decisions in the interest of profit and customer relations.
Today, not so much. Personal example... second largest building/home garden company in the country.
Recently went to purchase approximately $1,000 in furniture. Half hour with the salesperson, and after settling on what we wanted, asked about delivery charges. Salesperson and department manager both quoted a price and completed the sales form. We brought it to the "delivery" department, where they revised the delivery charge by upping the price by $10... a recent (yesterday) change. When I complained, instead of giving a courtesy $10 allowance to keep the sale, they refused to do this... I asked to speak to the manager, as I thought he'd want to keep a good customer... as well as the obvious profit.
"No way"...
So we left. The more I thought about it, the more I thought of how wasteful their policy was, so wrote a letter to the president of the corporation, asking if that was indeed their attitude and policy. I did receive a reply... which said they were sorry that I was disappointed, but that their manager had acted in accordance with their corporate instructions.
Policy trumps sanity...
