Is there a facility for re-ordering the same products?

Yes, you can repeat an order that you have made before. Go to "My Account" and under "Orders" click the "View My Order History" link. Select the order you want to repeat by clicking on the relevant "Web Ref." number. This will open the "Transaction Detail" page that lists the order details.

Click the "Repeat Order" button.
Please note that pricing and availability may have changed since you placed your last order. You have the opportunity to review your order before you place it.

You can also setup Quick Order Pads which you can copy and paste list of parts into.
