Back in the day (oh no, an old farts ramblings ahead) haggling was an accepted part of making "a deal".
In the city where I shopped there were 3 or 4 stereo shops within a mile or two of each other. When interested in an item I'd ask for "the best out the door price". Often times the response would be "I need to check with the manager" and the salesman would go off where he couldn't be seen, then return with a better price. "The manager says"...most times "the manager" was a small pocket calculator or even just pen and paper...had to figure his "spiffs" in then offer a price reduction.
If not completely satisfied I'd say, well, I'm from out of town, and I will be taking XXXX home with me, is that the best you can do? Sometimes the price would improve but not always.
With the variety of shops another bargaining ploy was "Well, I'm gonna head over to xxxxx and see what they have. I might be back."
Ah, brings back some good memories from my youth...
