In my real life, I manage a team building a set of ecommerce web sites for a large account computer reseller. You've never heard of us, but our web sites produce several hundred million dollars in revenue every year.
One of the development tasks I take care of myself is the catalog and pricing engine. What you're showing is a recurring nightmare of mine.
A few weeks back I had a bug that put VMWare right on our home page -- for free! Luckily I spotted it before any opportunists came along.
