That is all true, but misses the point that they slowed down service IN ADDITION to priorizing certain videos of limited supply. The slow down was INDEPENDENT of the supply, and the slow down was NOT DISCLOSED and was in violation of their explicit and implicit policy. This is NOT THE SAME THING as triage-ing patients according to their immediate medical needs. So, no cigar for you. But I do wish you well. Best of luck in all of your business dealings!

It's not just prioritizing videos, it's prioritizing the line. Somebody or something has to stick that DVD in the envelope and stick your address on the front and put it in the bucket to send. By the simple logic of reality that somebody or something has a limited number of units they can ship in one day, so they have to decide which customer's units should get the higher priority and therefore the highest chance for same day service and who should be at the back of the line and possibly have to wait a day.
And it is disclosed, it's in the terms of service.
It's exactly the same thing as triaging patients. You have a limited labor capacity and a quantity of labor to do that might or might not exceed your labor capacity, so you need to prioritize the labor deciding which customers need to be served first, second, third, and maybe tomorrow.
