Sometimes they find this frustrating. Coming from cultures in which prices are always elevated, in which the individual buyer works to get the best deal possible our low prices short circuit their logic. I had a customer last evening who just couldn't understand. He kept repeating "there must be a lower price." He said that a local, Mom & Pop carpet store had given him a total measurement 100 square feet less. I pulled out the floor plans we created and said "we use lasers, we are very precise," and showed him his square footage. He then said, "they are smaller, you are bigger, you should give a better discount," to which I said, "we will price match if you bring us a quote for the same type carpet." He mulled this over for about 2 minutes, and then said "no deal," got up and walked away.
Some of my fellow associates find this frustrating. I don't. This is how it is. I know some who have caved in order to get the sale, which sets a bad precedent. We have a customer right now who's managed to get markdown after markdown and, in the end, we will lose money because one person said "okay." I have had people threaten to take their business to our competitor and I've smiled and said, "go ahead;" rather they take the hit than us.
Either we will change or they will. Somehow I don't think we will start adjusting our sale's plan to account for haggling, so I suspect, in the end, they will have to stop saying "no deal."
