I'm sorry, but your logic makes very little sense again. The value of a deal is not measured in terms of some absolute metric but rather utility it brings to an individual. This is one of the fundamental principles the free market economics is based on. So it might be a fact that you get a better discount on a cruise to the Caribbean than a comparable cruise to Alaska, all things being equal. But if I hate beaches and don't care about summer weather, the lesser discount on the Alaskan cruise would be a better deal to me. Utility is not an absolute metric. So again, to determine the value of the 3x MR promotion, I have to consider cost / benefit ratio in the context of the alternatives available to me, not you or somebody else who might have different preferences and options. It is indeed YMMV.
