It has come to my attention that there is a massive bug in the shopping cart on this page. I recently updated the shopping cart I use and apparently it has a bug you could drive a mack truck through. Seriously. It’s huge.
Basically, if you want to order multiple personalized copies of the same book, the shopping cart system adds an additional book to your order. If you then click the buttons “Calculate Shipping & Taxes” or “Update Subtotal,” it will add another book to the order for every click that you do.
In short, for the time being anyway, if you want to order multiple personalized copies of the same book, you will have to order them separate to guarantee you are paying for exactly what you want. Apologies about this. Have already sent in a bug report to the people who supply my shopping cart so hopefully they will fix it immediately.
