The Walgreen’s near me sometimes lists prices in points. Companies use these rewards programs to muddy the waters of who has the best deal. They want you to buy their produce even if they’re more expensive because you’ve already bought into their rewards program. Its easy to say, Bob and Jim are selling the same product but Bob is $5 cheaper. But if Jim has a rewards program where you get compounding discounts over time as you buy more from them, it becomes real hard to do the math about who is really cheaper in the long run. It should be absolutely illegal or at least heavily regulated because its not only anti consumer, but undermines the free market by allowing companies to “lock down” customers with long term savings that can change over time. A free market makes it easy for consumers to make choices, not harder.
