I would argue that making an offer that you know cannot be fulfilled "We price match other retailers!" because you know other retailers don't carry that SKU for identical products because it is limited to your store is misleading/deception.

I walk into Best Buy thinking I can get a price match on a digital camera because they advertise price matching. They say sorry, "this is the Best Buy exclusive version of that very popular camera, we can't price match it. You see it comes with a special lanyard in the box." So I'm in a position where I've driven to Best Buy, and either have to pay their price or go home and order on Amazon. So maybe I pay their higher-than-Amazon price.

The price match was deceitful, they obtained money from it. Sounds like a swindle to me.

Fraudulently wasting my time is just as much of an issue. The wrong occurs when a store works to deceive me. Whether the deception is successful or not does not change the mortality of the action.
