Just wanted to update this: If you log on to bluesharmonica.com/hohner, the first thing you see is a registration form for the Hohner Newsletter to receive information on new products, events and promotions. If you scroll down, below it is a bar with the inscription “To the Free Online Lessons”. Click this to register with bluesharmonica.com, then enter the code on the insert which came with the instrument. The charge is then automatically deducted at the checkout and you can enjoy your free lessons. This system worked fine for me!
