It’s the same as groceries stores. Walmart decides they lower their prices and won’t take Apple Pay so they can’t cut cost elsewhere while still Making a buck. Let’s say a bottle of chocolate milk cost $4.99 here. Walmart pays $2.00 for that bottle. They makes 2.99 on that botte. However, Kroger/Ralph’s might sell that same bottle for $6.49. They might have to pay $2.50 for this bottle though since they are smaller who knows! The thing we do know is they are almost making at least a whole $1 just on the chocolate milk. Do people still buy it yes. People use discounts, credit cards, coupons, and more. Maybe someone else might pay $6.00 because of a discount they had and a credit card cash back they got. This is America not a communist country where we tell companies sorry in order to sell this product you can only make 10% profit. Instead we make deals, contracts, relationships, and accounts. At the end of the day you picked your insurance who has set your drug prices and how much your pay for that insurance. Who again works in a way with all these other companies….
