Re ordering something you have ordered off of us before is nice and simple.
1. First login to your account by clicking login in the top panel.
2. Once you are logged in you need need to click orders.
3. On the next screen you will be shown all of the orders you have ever placed on that account. Find the design you want to re-order and hit re-order.
4. From there you can then choose the options you require and then check out or add other items as normal.
