We completely agree with you - to put it mildly, the online order system is not easy to use. The goods news is: We are already working hard on a new version that will make things much easier!
I've sent you an email about your review and would love the opportunity to speak to you about it in more detail.
If in future you find it hard to place an order, you can always get in touch with me directly and I'll either help you place the order or place the order myself directly. I'm confident however that you'll find our new order system much easier to use, please allow me to update you on when we implemented it.
