Products can be easily added to a pending order from your 'shopping cart'. To do this sign in to your account and place the products you require in your cart. When you're done, in the shopping cart screen, click on the 'add to a pending order' button and follow instructions on the next page.

If you have a discount coupon activate it before you add the parts to the pending order to have the discount on the coupon otherwise you will not get the discount and we will not accept to manually add the discount afterwards.

When products are added to a pending order shipping cost for the order are recalculated and added if needed.

After adding the parts to the order you will be directed to the 'payment screen' to pay for the complete order or, when it is partially paid pay for, for difference (only the added products).
