Walmart is the same way. They won't honor internet prices in the store. Books-A-Million is the one that grinds my gears. The books I wanted were 1/2 the price online versus the retail store price. The clerk told me they are not even the same company!
It scalds me since everyone is all about shopping local and keeping the brick and mortar stores going, but the corporate suits sure don't make it easy for the customer to do.
