I guess I'm lucky. All I really need to do is express a "want" in something and my wife is all over me - go ahead and buy it...did you buy it yet...when does it arrive?

She knows that by the time I mention it to her, I've already done the shopping to find a good deal, checked the budget for issues and perhaps covered the cost by selling something that I no longer need or use.

It's sooo nice to have a trusting wife....and I've never broken that trust.
