#10 - Other.
It's never a matter of "asking permission" or "sneaking it past her" when I buy something. I pay the bills and monitor the budget, and her attitude is, if we can afford it, it's okay. We've both reached a point where we eschew using credit cards unless it's absolutely necessary (working on paying off the cards we have, and it's easier to do when not adding more to them), so some things end up waiting until we've saved up the money for them.
I really doubt my wife and I would have lasted 30 years so far as a couple if we played subversive games on each other over money and purchases. I don't care how cool a piece of gear might be, it ain't worth more than a harmonious home.
