Congratulations! I am always looking for the angle to improve the shop so I guess that makes me more shallow that all these other decent human beings.
As I see it, Now is the perfect time to explain to your wife that a Trend Airshield could make diaper changes a more pleasant experience. Just spray a little perfume on the filter and you have full dust and odor protection.
In a tight economy we must play all the angles to reach the goal of the perfect shop.
