Personally, I wouldn't ever lie to my wife about a purchase, but she was very supportive when I did some major upgrades last year. At this point I'm probably finished making expensive purchases and I think she'd rather that I just spend a few hundred bucks that talk to her about wanting something.
The key is to make sure that she knows that you will support her getting nice stuff to that she cares about. When we first got married I purchased her a new silver flute that was significantly better than the one she had and likely better than anyone she knows. That purchase was worth a lot to her because it showed that I valued things that she cared about. Most recently it was an upgraded iPod just because she wanted more memory.
I've heard more than once, "Whatever makes you happy."
