I don’t know how to say this. This is not fun for me. Wife is absolutely monitoring these expenses. It’s incredibly hard for me to make new purchases. And once I do, I have to listen to "you bought another XYZ, that looks and sounds just like the old one but it cost twice more!!!! etc." which is super painful. So as much I love math and humor (I have the biggest humor) I don’t get your point.
mmf was $449
I bought the Marantz for $150.
Any more questions?
