Wow! Has it always been this way or has it evolved into the suppliers dictating what you get to charge for the prescription drugs they sell to you? Guess that explains why several pharmacies sell much more than just prescription drugs.
Its why major grocery stores are able to service more insurance plans than smaller ones. When I dropped my employer insurance for Medicare Advantage, The Boss and I had to switch over to Publix. Star Market was not in network. Rarely do I go in just to get prescriptions. I usually walk out with $100 of groceries as well. To Publix, prescriptions are just a loss leader.
