> Costco’s loss leaders (e.g. the hot dogs) are also arguably instances of “messing with prices to gain customers.”
Except the article was a bit confusing on this point:
The biggest Costco loss leaders in America right now are rotisserie chicken, the hot dog & soda combo and gas. A Bloomberg article has calculated that Costco earns only $14 million in profit a year on its sale of 70 million chickens.
How is something a "loss leader" if it makes a profit of "only" $14 million?
However, as a consumer, I do agree with you in principle that they are messing with things, including pricing and placement of products, mostly to get people to buy more (possibly even to get customers in the doors), just to a lesser degree.
OTOH, the magnitude of that lesser degree is so great that it makes a difference. I know I'm not always getting the best deal if I buy any particular item at Costco, but I can be reasonably confident I'm not paying a huge markup.
In fact, I find Costco so reliable for fair pricing, I consider them my benchmark for seeing if other stores' discounts are really deals or just borderline scams like doubling the base price but offering an evergreen "sale" that's around 50% off. (Mostly only relevant to items with widely fluctuating prices or ones I buy so infrequently inflation is a factor).
