We have had to implement this, because alot of people never receive their email invoice, mostly due to spam filters not allowing them thru or deleting them as soon as they arrive.
The beauty of us doing this is now if you have a customer account with us, then all you need to do is login and you can view any of your previous orders and get the invoice shown again for printing. You will notice the customer accounts link now in the navigation for this reason.
Hopefully this will mean you will no longer need to make multiple orders to get your invoice now
