I often wondered how much it cost to hand write those price tickets but never doubted the added value. Another way to understand the difference between cost and value is to consider the difficulty faced by formula pricers. It's often easier to set a price by doubling one's cost than to find a price buyers are willing to pay. My best example is the paper tube problem. Everyone screamed at the cost accountants to fix the problem when they should have yelled at the marketing department.
Costs have nothing to do with value.
I opted for the lower price CPU, saving several thousand dollars. After a year of use, it became clear we needed the larger processing unit to keep up with the volume. So I paid the several thousand and a technician came out. He then flipped a little toggle and started to put the cover back on. To increase operating speeds, you just flip the extra switch.
