Add 15 to that. It’s moving. God love ya if you bought two cuz your wife probably won’t when she sees them show up. 
I am considering ordering a second one on my secret credit card and having it shipped to my parents house.
If I do that, my plan is to get my first one opened at my house on one shelf, and have the box displayed on a different shelf.
Then when she is gone one day, I will sneak to my parents house and pick up the second one. From there, I will flatten the "opened box" and store it away. The second barge that is still boxed will then slide into place on the shelf.
She would have no idea. Yes at some point, I will get caught but I think it's a risk I'm willing to take.
