Don't get sucked in by a luxurious showroom!
If this kind of thing didn't succeed, they wouldn't do it. But savvy shoppers shouldn't be impressed. Creating a nice shopping environment raises cost which often, in turn, leads to higher prices.
Wal-Mart's bare bones stores are one of the reasons it's able to offer such great deals -- The same thing goes for Costco.
So yeah -- putting greens and fresh pastries are lovely. But if your goal is to get a great deal, consider a more modest setting like the one in the picture. And head over to the luxurious dealers to play golf and sip espresso.
