Note: Locally, we have several furniture stores that all "guarantee the lowest price." The worse offender offered the 110% price match guarantee, since they were so sure they had the lowest prices. Actually, they duped a LOT of people with that... comparison shopping showed that they typically had the *highest* price in the area.
Anyway, I shopped around, found exactly what I wanted at one place, then went to one of the larger chain stores (Raymour and Flanagan - northeast chain) I went in on a night when they were really busy - they had one of those stupid leaders to get people into the store - they sent out thousands of keys in the mail, and "one of the keys will open the chest with $5000 in it." There was a line of literally hundreds of people stretching out the door, waiting for their chance. I was surprised at the turnout!
I found a clerk, "are you here for the promotional key thing?"
"Nope. We have a living room set we want to buy. It's xxxxxx style by Broyhill, we want fabric #xxxxx"
"I think we may have one of those in stock on the 2nd floor. Would you like to see it?"
"No. I know what it looks like. I want to know what your best price is on it."
5 minutes later, he returned and said "If I promise this is the lowest price you'll find anywhere, will you purchase it tonight, or are you just playing games with me so you can get the other place to do their price-match thing."
"Yes, I'll pay cash for it right now if it's a good price."
The price was barely more than half of the price on the floor in the other showroom. I saved a fortune.
Ironically, the only reason I looked for a new price was the original salesman wasn't going to cut me a break on the price when I bought and entire living room outfit - couch, love seat, and oak coffee table and end tables. When I inquired if there was a discount on an entire set (which I expected, since every complete set in the store had about a 20% discount when you buy everything), the guy was going to give me 10% off on the coffee table. We had the checkbook out, and decided to "we're going to think it over. We'll stop back later tonight."
