Is this a joke? [pricing gimmicks]

No, puffery is where you say something exaggerated. This slogan would be legally binding at least in Australia, but regardless it isn’t puffery because it’s not exaggerated, they would do exactly what they say they would do, it’s just that the circumstance in which they would have to do it will never arise.

The “policy” thing raised in this thread is a complete furphy: there does not have to be a policy. The slogan is completely self explanatory and self contained.

It’s more ingenious than that: it keeps prices high by punishing competitors for quoting lower prices. Any competitor that does so will cause their customer to come to the dealer making the $100 offer.

If the competitor is running the same deal, just keep running back and forth between shops—penny by penny—until it is free.

That’ll learn em.

It’s still a better tactic than the opposite

I refer you to Leonard v. Pepsico, Inc., one of the more memorable cases (along with the Carbolic Smoke Ball case) that almost all U.S. law students study in first year contracts class:

The Second Circuit denied Plaintiff’s claims on several grounds, including:

I don’t know how much the matresses in questions cost, but it’s possible that there was no contract if the cost exceeded the amount under which the written requirements of the statute of frauds (UCC 2-201) come into play.

What’s your point, as regards what I said, dofe?

I knew a tire salesman back in West Texas who I’m convinced murdered at least one of his competitors. Maybe two. Really.

Walmart in the States used to say they would beat any ones prices. However they do want to see the advertisement showing the price. I don’t think any business would just take your word for the price.

Not really. One thing I’ve noticed when I shop around for a particular product is:
a) they tend to be priced exactly the same regardless of what store you buy it at.

b) there are subtle differences in the product, often with a slightly different product or SKU to make exact side by side comparisons impossible (ie Model 101-R vs Model 101-J WidgetMaker)

I’m not sure why you think what you posted is a rebuttal of what I said, msmith537. Yes, your second point means that the effectiveness of the “we’ll beat our competitors’ prices” strategy is limited, but your first point is exactly an illustration of the effect the strategy has.
