When the counter guy's looking at his screen, he's seeing their cost as well as various price schedules. (Yes there's your walk in price,and my prefered resellers price. They don't mind at all to drop that price step. When they have to start dropping from that things start getting testy.) To meet a actual below their cost price match, you've just about got to show proof of that price forthem to match it. If the counter guy calls shift manager in to approve and HE calls store manager in for back up,,,,,, you know you've got em by the short hairs!
To which version of reality would you like to convert me?
