Yes, you can add multiple products to an order. Doing so can help you save on your shipping cost. For each additional item to order is calculated at the 'Additional Item' shipping price instead of the 'First Item' shipping price. But each order can only be shipped to one address. If you require shipping to different addresses, you will need to submit a new order for each shipping address.
After you have added an item to your shopping cart, return to the Zno homepage to work on your next photo product.
