We had a radio guy in Minnesota who talks about the 48 hour rule. If you bring something home and have it out in plain sight for 48 hours without anyone (usually wife) complaining about your purchase, you're in the clear. You get to say "What? That thing's been here for a long time."I found it much easier not to ask or tell my wife about a significant purchase than it is to request permission. I guess the old saying holds; It's easier to ask forgiveness than permission.
